Show Summary Details


Examples of simple flows are shown here, with emphasis on the validation of SPH from other numerical methods, theoretical solutions of Navier–Stokes equations or experimental data. The examples chosen cover a wide range of SPH capabilities, including rigid body motion in a fluid, free-surface water waves, steady confined flows, efforts on an obstacle, multi-phase flows, etc. The chapter gives particular attention to the modelling of open-channel flow, lid-driven cavity, waves induced by water collapse, and moving bodies. These test cases are frequently used by SPH modellers and are easy to reproduce. The chapter tests various numerical schemes, like weakly compressible and truly incompressible schemes, and test the effects of several physical models, like turbulence effects.
