摘要: 通过对一些关键技术的改进,特别是自由表面的判断方法和改进的固壁边界条件,使K2_SPH方法能够模拟破碎波问题,完整实现波浪的爬升、翻转、破碎等过程.对大幅液舱晃荡问题的模拟表明,K2_SPH方法较传统SPH方法在波形和压力分布都有明显改进.

Abstract: We introduce several improvements on key numerical techniques,especially for free surface identification and solid boundary handling method.They make K2_SPH simulating breaking waves successfully.It includes running-up,over-turning and breaking processes.Numerical test of violent tank sloshing shows that K2_SPH method is more accurate and reliable than traditional smoothed particle hydrodynamics(SPH) method for wave profile and pressure distribution.

Key words: smoothed particle hydrodynamics, K2_SPH, meshless method, breaking wave simulation
