Trends in the Development of Machinery and Associated Technology ” TMT 2014 , Budapest , Hungary 10-12 September , 2014 COMPUTATIONAL MODELING OF FREE-SURFACE FLOW PERTINENT TO DROPLET IMPACT ON A POROUS SUBSTRATE
The report is aimed at formulating and validating the computational model for the isothermal twophase flow with free-surfaces incorporating porous medium. The flow configuration consists of the liquid droplet impacting on and simultaneously spreading over and within a porous substrate. The interface capturing methodology implemented in the open-source software OpenFOAM based on the volume-of-fluid (VOF) model in the framework of Computational Fluid Dynamics (CFD) is extended to incorporate the flow within the porous medium. The potential of the model is evaluated by contrasting the results of numerical simulations to the existing experimental results.
