Numerical simulation of dynamics of droplet impact on heated flat solid surface

The process of the impinging of a droplet upon a heated flat solid surface was computationally studied to identify the key process occurring in a liquid droplet. A computational fluid dynamics model, based on the volume of fluid (VOF) approach, was used to simulate the impact of droplet dynamics on the heated flat solid surface. Surface tension and wall adhesion phenomena were taken into account in this model. The model was proved effective by comparing the simulation results with the experimental data in the literature. It could be concluded that the VOF-based model was able to simulate the dynamics of the impinging of a droplet upon a heated solid surface. The key characteristics of droplet evaporation and the interaction between the droplet and the solid surface could be captured.
