Abstract
The smoothed particle hydrodynamics (SPH) method is developed to simulate free surface and solidification problems. A new treatment is included to handle particles near the free and solidification interfaces. The method is applied to a droplet impacting on substrates with different roughnesses. Spreading, solidification, oxide redistribution, and droplet pinch-off are presented in two- and three-dimensional geometry configurations. This work demonstrates the SPH model as a powerful tool to study transport phenomena in problems with free surface deformation and solidification.
