Study on Prediction of Annular-Mist Flow Based on the Three-Fluid Model

3rd Report, Evaluation of Constitutive Equations of Deposition Rate of Droplet

Abstract

The correlation of droplet deposition rate is one of the most important constitutive equations in predicting the thermohydrodynamic behavior of annular dispersed flow based on the three fluid model. In view of this, quantitative comparison and evaluation of typical correlations of droplet deposition coefficient were made. The result indicated that the correlations show different dependencies on gas flux and droplet concentration and the considerable scattering in predicting the droplet deposition coefficient particularly for the higher gas fluxes and lower pressures.
