Abstract

<h2>Abstract</h2> In this talk we present numerical progresses for solving non-Newtonian free surface flows involving droplet dynamics. We revisit the construction of the front-tracking/marker-and-cell based schemes to deal with moving interface problems. The main purpose of our simulations is to investigate the combined effects of the viscoelasticity, plasticity, thixotropy, surface tension and gravity on the impact of droplets. In addition, we present some recent results in the collision dynamics of viscoelastic droplets. Finally, we describe a machine-learning based strategy for computing the curvature of the moving interface in the context of the front-tracking methodology.
