Numerical Study of Droplet Formation Time on Solid Surface

Abstract:

Microdroplets on solid surface are very common phenomenon in many engineering applications. The microdroplet formed from the fluid remaining on the column of micropillar after dewetting process. In this study, we generated microdroplet with various patterns and simulated the microfluidic dynamic processes based on a deforming body-fitted grid approach. The simulation results provide for explaining the effects of Capillary number and the liquid thickness on micropillar surface in the growing droplet diameter and microdroplet formation time.
