Evaporating Falling Drop

There-dimensional numerical simulations are carried out to investigate the dynamics of a drop undergoing evaporation and falling due to gravity. In order to accurately capture the interfacial phenomena dynamic adaptive grid refinement has been incorporated. The results are presented in terms of spatio-temporal evolution of the shape of the drop, along with the contours of the vapour concentration generated due to evaporation. This study has implications in natural phenomena, such as rainfall, dew formation and several industrial applications undergoing phase change. A parametric study of this phenomenon will be presented at the conference.
