Smoothed particle hydrodynamics modelling of fluids and solids

Abstract

The study is concerned about the application of the smoothed particle hydrodynamics (SPH) method within the computational fluid dynamics and elastodynamics. A brief description of the SPH model for an incompressible fluid and for an elastic solid is presented. The implemented model of incompressible fluid is tested for internal flows as well as for flows involving a free surface of the fluid. The implemented elastic solid model is examined during the simulation of the mechanical response of rubber rings.
