Abstract

In this paper, by defining an appropriate free energy function and integrate that with a Lattice Boltzmann algorithm; a two-phase system of vapor and liquid is modeled where the flow is governed by the continuity and Navier-Stokes equations. Using the developed model, initially a planar interface is modeled and outputs are compared with theoretical results. Then a droplet which is suspended in bulk vapor is investigated and equilibrium conditions of the droplet are compared with theoretical results.
