Simulation of Single Row of Droplets Impact on a Flat Surface Under High-overload Condition

Abstract

A tow-dimensional model has been developed of a row of droplets impact on a flat surface heated with constant power. The simulation based on VOF (volume of fluid) method is carried out to simulate the liquid film flow with no-phase-change heat transfer during droplets hitting the flat surface. A series of case with different droplets velocities and overload acceleration are calculated. The results obtained under highoverload and normal gravity conditions are compared to show the effect of acceleration on the heat transfer performance.
