Pressure Drop Characteristics of Flow Boiling in Microchannel With Low Aspect Ratio

Zhang Binglei,Xu Jinliang and Xiao Zejun

Strategic Study of CAE 2007, Volume 9, Issue 12,   Pages 86-93

Abstract: The present experimental data were compared with the predictions of the homogeneous flow model and separatedflow model respectively.The comparison indicates that the homogeneous flow model cannot predict the twophase pressure drop wellexcept using the twophase viscosity model of the Dukler correlation.model also failed to predict the twophase pressure drop in the microchannel of this study .
