【摘要】 采用欧拉－拉格朗日方法对黑石礁湾水交换能力进行了数值研究。根据理论分析，潮流速度场的剪变和潮流迟角的空间分布的不均匀性导致水质点在周期性潮流场中产生净漂移，从而引起相邻水体之间发生交换。数值计算结果表明，黑石礁湾的水体具有较强的交换能力，有利于湾内水体的更新。更多还原

【Abstract】 A numerical experiment has been performed by using Eulerian-Lagrangian method tostudy the tidal exchange in Heishijiao Bay.According to theoretical analyses,the net drift of particle in a periodic flow field is in-duced by the velocity shear and the spatial change of phase lag,so that the water exchangeoccurred in the neighboring waters,The numerical computational results indicated that thewaters exchange is strong which is advantageous to renewal of water in Heishijiao Bay.更多还原
