摘要
求解格林公式,在边界面上分布源汇,用数值解法在时域中模拟潜体近水面运动的三维兴波现象,通过试算确定了模型参数,并进一步讨论了潜体运动速度及其浸深对波形的影响,数值试验证实了用该方法来建立三维数值波浪水池的可行性和可靠性。
Based on Green＇s theorem, the wave making phenomenon reduced by a moving submerged body is simulated numerically with the time-stepping scheme by placing sources and sinks on boundary surface. The parameters of the simulation model are determined and the effects caused by the velocity and depth of the submerged body upon the wave pattern are discussed. By many numerical experiments, the method shows possibility and reliability on simulation of 3-D numerical wave tank.
