Beawer Barwari's research topic deals with the droplet motion on surfaces induced by external forces, for instance gravitation, shearing flow and vibration. Droplet dynamics is studied both experimentally and numerically. Insight on droplet behavior experimentally determined is eventually used for prescribing boundary conditions for the numerical model and for further validation. The numerical model bases itself on the Volume of Fluid (VoF) in OpenFOAM®
