Wetting phenomena and droplet-wall interaction modelling with Smoothed Particle Hydrodynamics approach

Abstract

Smoothed Particle Hydrodynamics (SPH) is a meshless CFD method, remaining a promising alternative for multiphase flow calculations due to straightforward interface treatment. In the present work we particularly focus on the accurate modelling of wetting phenomena and contact angles. For that purpose we modify the surface tension model in the neighbourhood of the triple line. The necessity of proper boundary conditions in SPH is discussed along the preliminary validation of proposed approach. Results show a great potential of the chosen method.
