Abstract:

为研究直立圆柱体的内孤立波载荷特性,依据三类内孤立波理论(KdV、eKdV和MCC)的适用性条件,使用内孤立波诱导上下层深度平均水平速度作为入口条件,采用Navier-Stokes方程为流场控制方程,建立了两层流体中内孤立波对直立圆柱体强非线性作用的数值模拟方法。系列计算结果表明,数值模拟所得内孤立波波形及其振幅与相应理论和实验结果一致,并且直立圆柱体内孤立波水平力、垂向力及其力矩数值模拟结果与实验结果吻合。直立圆柱体内孤立波载荷由波浪压差力、粘性压差力和摩擦力构成,其中摩擦力很小,可以忽略;对水平力,其波浪压差力与粘性压差力量级相当,流体粘性的影响显著;对垂向力,粘性压差力很小,流体粘性影响可以忽略。
