Sph shock wave
Web25. jún 2024 · The shock waves propagate into the surrounding medium, and then it reaches the free surface or fluid–structure region. In most cases, the peak overpressure is higher than the hydrostatic pressure. Hence, hydrostatic pressure is neglected and peak overpressure is considered as the peak pressure. WebThe Lagrangian smoothed particle hydrodynamics (SPH) method is used to simulate shock waves in inviscid, supersonic (compressible) flow. It is shown for the first time that the …
