一、引言 对于截面特征尺寸(比如圆柱的直径)与入射波长之比小于0.2的海洋建筑物或其构件,一般采用著名的Morison方程计算波浪荷载。Morison方程中包含两个水动力系数,即惯性力系数C_m和速度力系数C_D。几十年来,对于圆柱体的水动力系数的研究已经取得了许多有意义的成果。但是对于非圆柱体的水动力系数的研究却很有限。
I. INTRODUCTION For marine structures or their components whose cross-sectional feature dimensions (such as the diameter of a cylinder) and incident wavelength are less than 0.2, the well-known Morison equation is generally used to calculate wave loads. Morison equation contains two hydrodynamic coefficients, namely the inertial force coefficient C_m and the velocity force coefficient C_D. For decades, many interesting results have been achieved in the study of the hydrodynamic coefficients of cylinders. However, the research on the hydrodynamic coefficients of non-cylinders is very limited.
