Abstract
Droplet based digital microfluidics and its related studies are contemplated for many useful applications including lab-on-chip. The dynamics of such multiphase, multiphysics studies can be analyzed by lattice Boltzmann method (LBM). In this work, a pseudopotential based LBM framework for implementing EWOD actuation of droplet is explored by coupling the droplet and electrohydrodynamics.The effect of viscosity over the droplet spreading, merging, splitting is reported. The presented result can be useful in designing transportation, merging and splitting of the droplets. The results presented here shows that the modified pseudopotential-LBM can be used effectively for modeling EWOD and lab-on-chip applications.
