Numerical simulation of microscale foam

An integrated computational fluid dynamics model is developed to simulate all the elements of aqueous foam in microscale. The three-dimensional Navier-Stoke equation along with the continuity equations are used for this mode. The results of this model show the contribution of each element of the aqueous foam such as interior channels, exterior channels, film, interior node, exterior node, and Marangoni flow in the permeability of aqueous foam. The model can be extremely useful in the application of aqueous foam in the chemical and mineral industries along with the further study of foam including the effect of oil droplets and particles on the permeability of foams.
