Areas of Research and Areas of Study
Active areas of research in the Mechanical Engineering Department include: theoretical, numerical and experimental work in rarefied gas and plasma dynamics, electric propulsion, multiphase flows, turbulent flows, fluid-structure interactions, structural analysis, nonlinear dynamics and control, random vibrations, biomechanics and biomaterials, materials processing, mechanics of granular materials, laser holography, MEMS, computer-aided engineering systems, reconfigurable machine design, compliant mechanism design, and other areas of engineering design.
The graduate curriculum is divided into five distinct areas of study:
- Fluids Engineering
- Dynamics and Controls
- Structures and Materials
- Design and Manufacturing
- Biomechanical Engineering
These areas are parallel to the research interests of the mechanical engineering faculty. Graduate courses introduce students to fundamentals of mechanical engineering while simultaneously providing the background necessary to become involved with the ongoing research of the mechanical engineering faculty.
Students also receive credit for special topics under ME 593 and ME 693, and independent study under ISP. Faculty members often experiment with new courses under the special topics designation, although no course may be offered more than twice in this manner. Except for certain 4000-level courses permitted in the B.S./ Master’s program, no undergraduate courses may be counted toward graduate credit.
Programs of Study
The Mechanical Engineering Department offers two graduate degree options:
- Master of Science
- Doctor of Philosophy
For the M.S. program, applicants should have a B.S. in mechanical engineering or in a related field (i.e., other engineering disciplines, physics, mathematics, etc.).
The standards are the same for admission into the thesis and non-thesis options of the M.S. program. At the time of application to the master’s program, the student must specify his/her option (thesis or nonthesis) of choice.
For the Ph.D., a bachelor’s or master’s degree in mechanical engineering or in a related field (i.e., other engineering disciplines, physics, mathematics, etc.) is required.
The Mechanical Engineering Department reserves its financial aid for graduate students in the Ph.D. program or in the thesis option of the M.S. program.
When applying to the master of science program, students must specify their intention to pursue either the thesis or non-thesis M.S. option. Both the thesis and non-thesis options require the completion of 30 graduate credit hours. Students in the thesis option must complete 12 credits of thesis research (ME 599), whereas students in the non-thesis option may complete up to 9 credits of directed research (ME 598). The result of the research credits (ME 599) in the thesis option must be a completed master’s thesis. The number of directed research credits (ME 598) completed in the non-thesis option can range from 0 to 9.
In the thesis option, the distribution of credits is as follows:
- 9 graduate credits in mechanical engineering
- 12 credits of thesis research (ME 599)
- 3 graduate credits in mathematics
- 6 graduate credits of electives within or outside of mechanical engineering
In the non-thesis option, the distribution of credits is as follows:
- 18 graduate credits in mechanical engineering (includes a maximum of 9 credits of directed research—ME 598)
- 3 graduate credits in mathematics
- 9 graduate credits of electives within or outside of mechanical engineering
In either option, all full-time students are required to register for the graduate seminar (ME591) every semester.
Upon admission to the M.S. program, each student is assigned or may select a temporary advisor to arrange an academic plan covering the first 9 credits of study. This plan must be made before the first registration. Prior to registering for additional credits, the student must specify an academic advisor with whom the remaining course of study is arranged. The plan must be approved by the mechanical engineering graduate committee.
For students in the thesis option, the academic advisor is the thesis advisor. Prior to completing more than 18 credits, every student in the thesis option must form a thesis committee that consists of the thesis advisor and at least two other mechanical engineering faculty members from WPI with knowledge of the thesis topic.
The schedule of academic advising is as follows:
- Temporary advisor—meets with student prior to first registration to plan the first 9 credits of study.
- Academic advisor—selected by student prior to registering for more than 9 credits. For thesis option students, the academic advisor is the thesis advisor.
- Plan of Study—arranged with academic advisor prior to registering for more than 9 credits.
- Thesis committee (thesis option only) —formed prior to registering for more than 18 credits. Consists of the thesis advisor and at least two other mechanical engineering faculty members from WPI.
This schedule ensures that students are well advised throughout the program, and that students in the thesis option are actively engaged in their research at the early stages of their programs.
Each student in the thesis option must defend his/her research during an oral defense, which is administered by an examining committee that consists of the thesis committee and a representative of the mechanical engineering graduate committee who is not on the thesis committee. The defense is open to public participation and consists of a 30-minute presentation by the student followed by a 30-minute open discussion. At least one week prior to the defense each member of the examining committee must receive a copy of the thesis. One additional copy must be made available for members of the WPI community wishing to read the thesis prior to the defense. Public notification of the defense must be given by the mechanical engineering graduate secretary. The examining committee will determine the acceptability of the student’s thesis and oral performance. The thesis advisor will determine the student’s grade.
Changing M.S. Options
Students in the non-thesis M.S. option may switch into the thesis option at any time by notifying the mechanical engineering graduate committee of the change, provided that they have identified a thesis advisor, formed a thesis committee, and have worked out a Plan of Study with their thesis advisor. Subject to the thesis advisor’s approval, directed research credits (ME 598) earned in the non-thesis option may be transferred to thesis research credits (ME 599) in the thesis option.
Any student in the thesis option M.S. program may request a switch into the non-thesis option by submitting the request in writing to the mechanical engineering graduate committee. Before acting on such a request, the graduate committee will require and seriously consider written input from the student’s thesis advisor. Departmental financial aid given to the thesis-option students who are permitted to switch to the non-thesis option will automatically be withdrawn. Subject to the approval of the mechanical engineering graduate committee, a maximum of 9 credits of thesis research (ME 599) earned by a student in the thesis option may be transferred to directed research credit (ME 598) in the non-thesis option.
The course of study leading to the Ph.D. degree in mechanical engineering requires the completion of 90 credits beyond the bachelor’s degree, or 60 credits beyond the master’s degree. For students proceeding directly from B.S. degree to Ph.D. degree, the 90 credits should be distributed as follows:
|Courses in M.E. (incl. Special Topics and ISP)||15 credits|
|Courses in or outside of M.E.||15 credits|
|Dissertation Research (ME 699)||30 credits|
| Additional coursework
Additional Dissertation Research (ME 699)
Supplemental Research (ME 598, ME 698)
For students proceeding from master’s to Ph.D. degree, the 60 credits should be distributed as follows:
|(incl. Special Topics and ISP)||12 credits|
|Dissertation Research (ME 699)||30 credits|
Additional Dissertation Research (ME 699)
Supplemental Research (ME 598, ME 698)
In either case, the result of the dissertation research must be a completed doctoral dissertation. Only after admission to candidacy may a student receive credit toward dissertation research under ME 699. Prior to admission to candidacy, a student may receive up to 18 credits of predissertation research under ME 698. All full-time students are required to register for the graduate seminar (ME 591)every semester.
Upon admission to the Doctoral Program, each student is assigned or may select a temporary advisor to arrange an academic plan covering the first 9 credits of study. This plan should be arranged before the first day of registration.
Prior to registering for any additional credits, the student must identify a permanent dissertation advisor who assumes the role of academic advisor and with whom a suitable dissertation topic and the remaining Plan of Study are arranged. Prior to completing 18 credits, the student must form a dissertation committee that consists of the dissertation advisor, at least two other mechanical engineering faculty members, and at least one member from outside the department. These committee members should be selected because of their abilities to assist in the student’s dissertation research.
The schedule of advising is as follows:
- Temporary advisor—meets with student prior to first registration to plan first 9 credits of study.
- Dissertation advisor—selected by student prior to registering for more than 9 credits.
- Program of study—arranged with Dissertation advisor prior to registering for more than 9 credits.
- Dissertation committee—formed by student prior to registering for more than 18 credits. Consists of dissertation advisor, at least two M.E. faculty, and at least one outside member.
This schedule ensures that students are well advised and actively engaged in their research at the early stages of their programs.
Admission to Candidacy
Admission to candidacy will be granted when the student has satisfactorily passed a written exam intended to measure fundamental ability in three of the following five curriculum areas: fluids engineering, dynamics and controls, structures and materials, design and manufacturing, and biomechanical engineering. The three areas are selected by the student. The exam is given in January. For students who enter the program with a bachelor’s degree, the exam must be taken after three semesters if they began their studies in the fall, and after two semesters if they began in the spring. For students who enter the program with a master’s degree, the exam must be taken after one semester if they began in the fall, and after two semesters if they began in the spring. Students in the M.S. program who plan to apply for fall admission to the Ph.D. program are strongly advised to take the candidacy exam in January before that fall. The details of the examination procedure can be obtained from the mechanical engineering graduate committee.
Each student must prepare a brief written proposal and make an oral presentation that demonstrates a sound understanding of the dissertation topic, the relevant literature, the techniques to be employed, the issues to be addressed, and the work done on the topic by the student to date. The proposal must be made within a year of admission to candidacy. Both the written and oral proposals are presented to the dissertation committee and a representative from the mechanical engineering graduate committee. The prepared portion of the oral presentation should not exceed 30 minutes, and up to 90 minutes should be allowed for discussion. If the dissertation committee and the graduate committee representative have concerns about either the substance of the proposal or the student’s understanding of the topic, then the student will have one month to prepare a second presentation that focuses on the areas of concern. This presentation will last 15 minutes with an additional 45 minutes allowed for discussion. Students can continue their research only if the proposal is approved.
Each doctoral candidate is required to defend the originality, independence and quality of research during an oral dissertation defense that is administered by an examining committee that consists of the dissertation committee and a representative of the mechanical engineering graduate committee who is not on the dissertation committee. The defense is open to public participation and consists of a 45-minute presentation followed by a 45-minute open discussion. At least one week prior to the defense, each member of the examining committee must receive a copy of the dissertation. At the same time, an additional copy must be made available for members of the WPI community wishing to read the dissertation prior to the defense, and public notification of the defense must be given by the mechanical engineering graduate secretary. The examining committee will determine the acceptability of the student’s dissertation and oral performance. The dissertation advisor will determine the student’s grade.
The Combined Bachelor’s/Master’s Program
The Mechanical Engineering Department offers a B.S./Master’s program for currently enrolled WPI undergraduates. Students in the B.S./Master’s program may choose either the thesis or non-thesis M.S. option. The department’s rules for these programs vary somewhat from the Institute’s rules. For students in the B.S./Master’s program, a minimum of six credits and a maximum of twelve credits may be counted toward both the undergraduate and graduate degrees. At least six must be from graduate course credits (including graduate-level independent study and special topics courses), and none may be from courses lower than the 4000-level. No extra work is required in the 4000-level courses. A grade of B or better is required for any course to be counted toward both degrees.
The application for the B.S./Master’s program must include a list of courses that the applicant proposes to count toward both his/her undergraduate and graduate degrees. In most cases, the list consists of courses that the applicant will take in the senior year.
Applications will not be considered if they are submitted prior to the second half of the applicant’s junior year. Ideally, applications (including recommendations) should be completed by the early part of the last term (usually D-term) of the junior year.
Acceptance into the B.S./Master’s program means that the candidate is qualified for graduate school, and signifies approval of the courses listed for credit toward both the undergraduate and graduate degrees. However, admission is contingent upon the completion of six graduate credits (from the submitted list) with grades of B or better in each. If grades of C or lower are obtained in any other listed courses, then they are not counted toward the graduate degree, but the applicant is still admitted to the program.
Students in the B.S./Master’s program who choose the thesis M.S. option are encouraged to pick a thesis area of research that is closely related to the subject of their major qualifying project. Those students in the B.S./Master’s program who complete their B.S. degrees in May and choose the thesis option are encouraged to begin their thesis research during the summer immediately following graduation.
A detailed written description of the B.S./ Master’s program in mechanical engineering can be obtained from the mechanical engineering graduate secretary.

Vacuum Test Facility (VTF)
Also located in the Aerospace Laboratory is the Vacuum Test Facility (VTF). The VTF is designed to support ongoing research and educational activities requiring a controlled vacuum environment. The cornerstone of this facility is a 50 in diameter, 72 in long stainless steel vacuum chamber which will enable the creation of a vacuum environment for use in the characterization of electric and chemical thruster performance, investigation of neutral and ionized gas plume expansion in a vacuum, and testing of avionics for nanosatellites designed to operate in a vacuum environment.
The pumping system for the VTF includes a rotary mechanical pump, positive displacement blower combination capable of providing substantial pumping speed (>560 liters/sec ) at low vacuum (10-2 - 10-3 Torr). This pump pair can be used for tests requiring relatively high mass flow rates, such as plume measurements on micro- chemical thrusters. For tests of electric thrusters where lower pressures (higher vacuum) are required, the mechanical pump would be used initially to pump the system down to the milli-Torr pressure range. Pumping would then transition to a 20” cryopump which can provide up to 10,000 liters/s (on N2) at pressures less than 10-6 Torr.
