THE RESULTS CONTRAST WITH DIFFERENT THEORY FORMULA OF SECOND-ORDER DIFFRACTION WAVE FORCE

  • 摘要: 该文研究了一种简单快速回转体的二阶波浪力计算方法,并给出了直立圆柱和截断圆柱的二阶波浪力的计算结果,将所得计算结果与其它3种不同的理论公式的结果进行了对比,验证了该文计算方法的正确性。因该文方法不涉及自由表面上无穷积分,表达式简单、计算速度快,所以更适合快速计算二阶速度势所引起的二阶波浪力。

     

    Abstract: A simple and fast method to calculate the second-order wave force on an axisymmetric body is studied, and the results of the vertical cylinder and the truncated cylinder’s second-order wave force are attained. The results obtained with the other three different theoretical formulas are compared to verify the correctness of this method. Because this method does not involve a free surface infinite integral, and has a simple expression and high computational efficiency, it is more suitable for fast calculating second-order wave forces caused by second-order potential.
