Prediction of Mass Quality in Boiling Flow for High Inlet Subcooling

The prediction of mass quality in boiling flow is significant for the calculation of phase distribution in diabatic two-phase flow. A new predictive model for the mass quality for high inlet subcooling is developed in this paper by the analysis of heat balance equation, and correlation for the onset of saturated boiling is also proposed in this model. The comparison between experimental data and predictive results shows that this model can predict mass quality successfully in boiling flow.
