Heat Transfer Enhancement in Small-Scale Devices: A Collaborative Experimental/Numerical Approach

摘要

The aim of the project has been the analysis of spinodal decomposition of binary liquid mixtures for heat transfer enhancement in micro- devices. The work has followed two main lines and approaches: experimental investigation of heat transfer in small scale heat exchangers and numerical modeling to build a designing tool. For the first approach, the results show a significant increase of heat transfer efficiency up to 100% compared to conventional techniques, indicating that spinodal-mixture-based heat exchangers are a promising way to dissipate high specific heat fluxes in micro-electronics and small scale devices. For the second approach, we started developing a novel theoretical modeling approach that eventually will allow us to design efficient heat exchangers (based on the spinodal enhancement effect).
