Development of Modeling Methods and Tools for Two-Phase Cooling Systems

In this proposal ThermoAnalytics and Clemson University have jointly proposed to develop a modeling capability for two phase electronics cooling that would use the commercial thermal analysis package MuSES as a framework. Three high level tasks are defined in the work plan. In Task 1 component models for a microchannel heat sink and a spray cooling device will be developed. These will be drawn from the technical literature. In Task 2 the existing fluid stream feature in MuSES will be enhanced to include a fully time accurate, two phase flow capability. A key technical challenge in this task is the implementation of a time accurate numerical solver for one dimensional two phase flow. Task 3 consists of testing program, to be carried out at Clemson University, for the purpose of validating the models. This testing program will be lead by Dr. Jay Ochterbeck, professor of mechanical engineering at Clemson.
