MULTIPHASE SPH SIMULATION FOR INCHAMBER IMPACT PRESSURE ON VERTICAL BREAKWATER WITH WAVE ABSOPTION CHAMBER

نویسندگان

چکیده

A numerical model of a vertical breakwater integrated with wave absorption chamber has been tested against regular in virtual flume. The open source Smoothed-Particles Hydrodynamics, or SPH, (Lagrangian type) software called DualPSHysics was deployed for the simulation. Both multiphase (air-water) and single-phase (water only) fluid were considered compared an experimental result. Single-phase capture water column elevation within ratio 0.92 0.70, respectively, when to experiments. However, is not able fully closed effect. It found that inside chamber, SPH captures maximum (compressed) well but overestimates air compression by factor 1.5.

GPU-SPH simulation of Tsunami-like wave interaction with a seawall associated with underwater

Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to...

Numerical simulation of wave impact on a rigid wall using a two-phase compressible SPH method

In this paper, an SPH method based on the SPH–ALE formulation is used for modelling two-phase flows with large density ratios and realistic sound speeds. The SPH scheme is further improved to circumvent the tensile instability that may occur in the SPH simulations. The two-phase SPH solver is then used to model a benchmark problem of liquid impact on a rigid wall. The results are compared with ...
