Chute de pression diphasique et taux de vide dans des microcanaux : prévision grâce à une analyse de la distribution du régime d'écoulement fondée sur la probabilité.

Probabilistic two-phase flow map pressure drop and void fraction models are developed for 6-port microchannels in order to providea 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 10°C saturation temperatures, qualities from 0 to 1, and mass fluxes varying from 50 to 300 kg/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.
