Description
After the seminar, from 15:00 to 17:00, there will be a round table discussion
with Prof. Thome where you can bring up your specific issues
The seminar will begin with an introduction of the Laboratory of Heat and Mass Transfer (LTCM) at the EPFL, a laboratory composed of about 20 researchers including phd’s and post-docs. Single-phase and two-phase microscale heat transfer will first be overviewed with some discussion on the pros/cons of each type of flow, followed by more focus on two-phase microscale heat transfer. In particular, the LTCM lab is specialized in experimental investigation, analytical modeling and numerical modeling of these flows in single-microchannels and in multi-microchannel cooling elements for applications to cooling of computer chips, power electronics, etc. Videos of flow boiling in multi-microchannel cooling elements will be shown with poor distribution and with excellent distribution. In particular, LTCM has extensive experience and methods for predicting two-phase heat transfer and supercritical heat transfer and flow of refrigerant and CO2 in microchannels. Other topics that will be addressed are: choice of coolant for working fluids in electronic cooling systems, mass reduction of the cooling system and working fluid, local hot spot cooling, forced flow operation (with pump) vs. thermosyphon operation (passive flow due to gravity), and cooling system design and simulation.
