WebMay 29, 2024 · Marrone et al. [ 15] adopted a Riemann-ALE-SPH method to simulate high-speed water entry of plates with different ditching configurations. They considered three main parameters, the horizontal velocity, the pitch angle and the approach angle during these water entries. WebAn approach to the Riemann problem for SPH inviscid ideal flows a reformulation for the state equation Received: date / Accepted: date Abstract In the physically non viscous fluid dynam-ics, ”shock capturing” methods adopt either an artificial viscosity contribution or an appropriate Riemann solver algorithm.
http://sait.oats.inaf.it/MSAIS/1/PDF/36.pdf Another way to determine the density is based on the SPH smoothing operator itself. Therefore, the density is estimated from the particle distribution utilizing the SPH interpolation. To overcome undesired errors at the free surface through kernel truncation, the density formulation can again be integrated in time. The weakly compressible SPH in fluid dynamics is based on the discretization …
