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.
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.
