Development and experimental validation of simple methodologies for modelling of flow boiling in microchannels with large pressure drop

Abstract

Everything should be made as simple as possible but not simpler Inspired by Albert Einstein s famous quote this thesis proposes simple but accurate approaches to model the complex interplay between the various thermophysical phenomena occurring in flow boiling The proposed methodologies incorporate the effect of flashing and local thermophysical properties on two phase pressure drop evaluation and hence on heat transfer prediction The governing equations are derived in an elegant close fo...
