Random and geometric model of droplets nucleation on textured surfaces

Résumé

The aim of this study is to simulate dropwise condensation in order to control the rate of droplets nucleation and growth. The process of dropwise condensation attracted lots of attention since about 80 years ago, when Schmidt et al. proved that its heat transfer coefficient is significantly higher than filmwise condensation. Dropwise condensation is preferred when higher rate of heat transfer is needed. The problem that we are dealing with is the formation of liquid droplets in car light shield which will cause the light reflection, in such cases it is preferred to achieve the filmwise regime. In this research we are going to develop a computer algorithm to simulate spatial distribution as well as growth rate of droplets at each time step. The results of the presented algorithm are validated by comparing with the experimental data and spatial distribution in Poisson point process.
