Inclusion of an acoustic damper term in weakly-compressible SPH models

The proposed work describes a novel viscous term specifically conceived to reduce the amount of acoustic pressure waves in weakly-compressible SPH models. above-mentioned only acts on component field, which is generated as consequence liquid impacts and assumption that fluid weakly-compressible, whereas it leaves incompressible-like unchanged. In comparison existing regularizing terms literature, this allows for noise-free simulations are similar incompressible flows, and, at same time, maintains advantages explicit schemes (i.e. scalability easiness parallelization). damper converges zero when particle resolution increases, recovering consistency with Navier-Stokes equations. Numerical results demonstrate effective flow different
