Web14 Oct 2024 · Sun et al. (2024) developed a + -SPH method, which introduced a Particle Shifting Technique (PST) into the -SPH method. ... Numerical simulation of landslide generated impulse waves using a... WebIn this work we present a δ-Smoothed Particle Hydrodynamics (SPH) scheme for weakly compressible flows with automatic adaptive numerical dissipation. The resulting scheme is a meshless self-adaptive method, in which the introduced artificial dissipation is designed to increase the dissipation in zones where the flow is under-resolved by the numerical …
