Title: Numerical investigation of liquid sloshing in a 2D rectangular tank based on SPH method
Abstract: When the forced frequency is close to the natural frequency of the free surface,liquid can cause violent motion in the tank.Based on smoothed particle hydrodynamics(SPH)method,numerical research on the liquid sloshing in a 2Drectangular tank under sway and roll excitations with shallow filling level is carried out at 4forced frequencies near the resonant frequency of the free surface,respectively.Comparing the global free-surface profiles and the time histories of the slamming pressure for both numerical and experimental studies,it is found that SPH method can simulate the global free-surface scenarios,such as hydraulic jump,breaking wave and so on with large deformation motion.Furthermore,this numerical method can simulate and give a good prediction of the characteristics for the slamming pressure under non-resonant forced frequencies.It is suggested that two-phase simulation should be introduced in SPH method in order to simulate the violent liquid sloshing under resonant frequency.
