Richard Sisson Jr.

Richard D. Sisson Jr., Yiming (Kevin) Rong, Gang Wang, Bowang Xiao, and Qiqui Wang have been granted a patent by the US Patent and Trademark Office for their patent application "Systems and Methods for Predicting Heat Transfer Coefficients During Quenching". Sisson and Rong are faculty members in the Mechanical Engineering Department at Worcester Polytechnic Institute (WPI).

Richard D. Sisson, Jr. is Dean of Graduate Studies, George F. Fuller Professor, and Director of Manufacturing and Materials Engineering.

Yiming (Kevin) Rong is the John W. Higgins Professor of Mechanical Engineering, Associate Director of the Manufacturing and Materials Engineering Program, and the Director of the Computer-aided Manufacturing Laboratory (CAM Lab).

Yiming Rong

Professors Sisson and Rong are the principle investigators for several research projects in the ME Department. Dr. Sisson's main research interest is the application of the fundamentals of diffusion kinetics, modeling, and thermodynamics to the solution of materials problems. Dr. Rong’s research area is Computer-aided Manufacturing, including Manufacturing Systems, Machining and Heat Treatment Processes, and Computer-aided Fixture Design (CAFD).

The approved patent "Systems and Methods for Predicting Heat Transfer Coefficients During Quenching" provides a method to predict heat transfer coefficients for metal castings during quenching and/or cooling. When the obtained HTC values are optimized for a particular quench condition, a set of semi-empirical equations can be used to quickly modify the standard/baseline HTC data for different conditions.
