Numerical simulation of flows with moving contact lines

Résumé


The main objective is to develop and use a 3D computational method for such flows. The contact-line model should be such that it can be used for practical applications. Current computational models for such flows either don’t allow this, or are 2D. As a basis we use the freeware TPLS  which is a two-phase flow solver but for flows without moving contact lines. Thus far, we have revisited the issue of mass conservation (that is, for incompressible flow, the volume occupied by each fluid should be conserved, which is a computational challenge). Next, a new computational model has been developed for 3D flows with contact lines. The resources have been used mostly for smaller (test) runs, the main runs are on Occigen (and Jade previously). This work is financed by IFPEN.
