Abstract:
In this study a new SPH model for solving free surface and fluid-fluid interaction problems is presented. The numerical model is capable of simulating two dimensional hydraulic problems with arbitrary boundary and initial conditions and large number of particles. It has the ability to model multi-fluids domain with different densities and viscosities. Several corrections are implemented in SPH formulation such as treatment of free surface and correction of viscous term in order to conserve the angular momentum. Several examples are conducted in fluid-fluid domains to measure the capability of model in this area of study. This new model use Incompressible SPH method for more accurate simulation of free surface. As far as the authors of this study concerned, most of the recent models use compressible SPH method in order to solve Fluid-Fluid interaction problems. Presented model ability to simulate different phenomenon with arbitrary boundaries and initial conditions, make it possible to solve most of physical problems on multi-Fluids domain
