ABSTRACT

We model and simulate numerically a droplet impact onto a solid substrate. The triple line dynamics modeling is implicit (as opposed to classical explicit mobility relations); it is based on the Shikhmurzaev equations. These equations include generalized Navier slip type boundary conditions with extra local surface tension gradient terms. Numerical results when spreading are presented. A particular attention is paid to flow patterns near the contact line.
