Abstract

Two different boundary condition treatments-mirror boundary conditions and static boundary conditions are implemented to simulate lid-driven cavity flow with incompressible SPH (ISPH) algorithms. The algorithms include density-invariant ISPH (ISPH-DI) and divergence-free ISPH (ISPH-DF). The results show that simulations are more accurate with the static particles boundary and the ISPH-DF algorithm is more stable than the ISPH-DI algorithm.
