Simulation of Water Droplet Impact using OpenFOAM®

Droplet impact on the solid surface has been the notable research study in the field of fundamental sciences that encounter in the natural and industrial phenomena. With the present day advancements, the computational simulation of Droplet interaction with the solid surface expounded the under-lying flow physics inside the droplet also. In the present study, the water droplet impacting at the Weber Number, We =, was experimentally carried out. The detailed flow phenomenon was also captured using the numerical technique in the OpenFOAM®. The spreading behavior of water droplet upon impacting the hydrophobic surface was reported here. The temporal variation of the droplet in both the numerical and experimental studies evinced that except maximum spread regime, other regimes were closely matching. The equilibrium condition of the droplet is in puddle shape in the experimental whereas the simulation results show the Hemi-spherical hat.
