Experimental investigation of binary mixture flow boiling in micro-channels.

摘要

An experimental study is performed to investigate flow boiling heat transfer characteristics of methanol-water mixtures in micro-channels. The test section contains 24 parallel channels having a 200 mum x 400 mum cross-section. Tests are conducted with pure water and methanol as well as five methanol-water binary mixtures with methanol molar fraction ranging from 18% to 76% over a mass velocity range of 275.868 kg/m2s and at an inlet temperature of Tin=Tbubble-20&
