Developing a Standard Smoothed Particle Hydrodynamic Model for Free Surface Flows

In This paper a Lagrangian model is presented based on weakly compressible SPH method used for simulation of free surface flows with violated changes in free surface. Dam break in a closed tank was simulated here as one of the main test cases for validation of the free surface flow model and its results were compared with the experimental data, analytical solutions, and previous numerical results. Also, in order to study the effects of viscosity, the shear flow between two parallel plates (Couette flow) and shear cavity flow are modeled and the results were compared with the available analytical and numerical results. All comparisons showed the power of the developed model in modeling free surface and shear flows.
