摘要
非静压波浪模型是一种近年来得到迅速发展且有望在工程计算中获得广泛应用的波浪模型。为了在非静压波浪模型中实现无反射造波,在连续性方程中添加了质量源项进行域内源造波,并采用阻尼消波方法进行数值消波。数值算例结果表明,所建立的无反射造波方法可以较好地避免非静压波浪数学模型中的二次反射,实现长时间稳定波浪模拟。
The non-hydrostatic wave model has been rapidly developed in recent years and is expected to be wildly applied in wave simulation for engineering problems.A numerical wave generation method without re-reflection for non-hydrostatic wave model is developed through introducing a mass source in the continuity equation combined with wave damping absorber in computational domain.The results of numerical simulation examples show that the presented non-hydrostatic wave model can avoid wave re-reflection effectively and simulate waves stablely for a long time.
