Numerical analysis of film boiling from a heated plate facing downwards in saturated water : Effect of vapor flow at the edge of the plate on the vapor film configuration

Abstract

An numerical analysis was made on film boiling from a heated plate facing downwards immersed in saturated water using the SOLA-VOF method. In this calculation the LC method was also used in order to take into account the compressibility of vapor and liquid. The horizontal vapor film thickness was treated as the boundary condition, and the numerical solutions were obtained for the case of the constant degree of the wall superheat. The effect of the horizontal vapor film thickness on the trend of the heat transfer rate and vapor flow rate were investigated.
