Professor Amitabh Narain received $297,288 from the National Science Foundation, Advanced Power Systems Research Center, for a three-year project, “Flow Prediction and Fluctuation-sensitivity Investigations for Quasi-steady Shear Driven Condensing Flows in Milli-meter to Micro-meter Scale Two-Phase Systems.”
Reliable designs of modern micro-scale-phase-change thermal systems require effective integration of condensers. For that, system designs need to overcome difficulties in attaining and maintaining shear driven quasi-steady condensing flows with repeatable performance. Besides assurance of repeatable performance of the condenser, good and reliable flow prediction capabilities should be made available for micro-scale or shear driven condensers. Such reliable estimates are needed for sizing and matching the condenser into any system of choice. Development of the proposed research takes the current research forward towards addressing these two issues of repeatability and flow predictability for shear driven and/or micro-scale condensing flows. The research on condensing flows will also be helpful in addressing analogous issues for annular flow regimes in micro-scale flow boilers.
