Title: Prediction of Two-Phase Pressure Drop and Void Fraction in Microchannels Using Probabilistic Flow Regime Mapping
Author(s): Jassim, E.W.; Newell, T.A.
Subject(s): pressure drop heat transfer microchannels two-phase flow void fraction
Abstract: Probabilistic two-phase flow map pressure drop and void fraction models are developed for 6-port microchannels in order to provide a more accurate and common means of predicting void fraction and pressure drop. The models are developed for R134a, R410A, and air-water in 6-port microchannels at 10o C saturation temperatures, qualities from 0 to 1, and mass fluxes varying from 50 to 300kg/m2-s. The probabilistic flow map models developed are found to accurately predict void fraction and pressure drop for the entire quality range and for all three fluids.
