Drs. Chirag Kharangate and Yasu Kamotani Awarded NASA STTR Phase II Grant

Chirag Kharangate, Assistant Professor and Yasuhiro Kamotani, Emeritus Professor have been awarded a new grant titled "Hot Reservoir Variable Conductance Heat Pipe with Enhanced Fluid Management Features".

Funded at $750K, the grant is a collaborative effort between the company Advanced Cooking Technologies, Inc. (ACT) and CWRU.  Chirag serves as the faculty PI and Yasu is a Co-PI.  Their share of the funding is $231K.

As background information, NASA’s plans to further expand human and robotic presence in space and planetary surface automatically involve significant thermal challenges. A hot reservoir variable conductance heat pipe (VCHP) that can provide much tighter passive thermal control capability is an ideal thermal management device for future planetary landers and rovers. In the STTR Phase I project, Chirag’s team and ACT performed a fundamental study to understand the complex fluid transport phenomena within a hot reservoir VCHP, based on which they proposed a novel loop-based concept for the hot reservoir VCHP. At the end of this new project, a prototype-flight LHR-VCHP will be developed for planetary landers and rovers thermal management.
