|A meshless particle code based on the Smoothed Particles Hydrodynamics (SPH) method has been developed. It is capable of simulating shear driven flows, free surface flows and two-phase flows of incompressible liquids using the Weakly Compressible SPH approach. Benchmark-tests of shear flows for validation of periodic boundary conditions and the viscosity model were conducted. By applying a modified Tait equation it is possible to account for surface tension effects. |
With this prerequisite the simulation of a two-dimensional liquid jet with fluids of different viscosities using the artificial viscosity model was conducted. Preliminary results are presented which underline the promising performance of this approach. Our final goal is the generation of a so called virtual atomization test rig, which provides the possibility to simulate three-dimensional flow dynamics during the atomization process of various fluids.
