NASA Funds WPI Space Station Project

Professor Jamal Yagoobi (PI) has received a $485K grant award for a NASA-funded project exploring the effects of gravity on the interaction of electric and flow fields.

Professor Jamal Yagoobi (PI) has received a $485K grant award for a project funded by NASA entitled,  “A Two-Phase Heat Transport Device Driven by Electric Conduction Mechanism in Micro- and Macro-Scales.”  The main objective of this project is to develop fundamental understanding and physical models to characterize the effects of gravity on the interaction of electric and flow fields in the presence of phase change.  Specifically, the effects of absence gravity on the electrically generated two-phase flow and on electrically driven liquid film boiling will be explored.  In the absence of gravity, there will be no mechanism to move the bubbles away from the heated surface.  However, the electrically driven liquid film is expected to repel these bubbles away from the surface allowing for effective heat transfer from electronics operating in space.  Terrestrially, this concept is expected to result in removing heat at rates far exceeding 500 W/cm2 impacting the development of next generation electronics.

The development approach to accomplish the above stated objectives is a) to conduct preliminary experiments in low gravity flights and ground-based facilities to refine technique and to obtain preliminary data for model development and b) to design for Fluid Integrated Rack on International Space Station (ISS).  Autonomous operation employing minimal ISS resources will be utilized.  Telemetry will be viewed on the ground.  The targeted date to conduct this experiment on ISS is 2017.
