| 摘 要： | 本文通过实验研究,基于Morison方程和线性波理论,探讨了在规则波和水流共同作用下作用于垂直圆柱上的横向力,它与正向力的关系以及它对总力的影响。根据KC数的重新定义值,文中给出了合力系数C_l、速度力系数C_d、惯性力系数C_m、升力系数C_L及升力主导频率与KC数的相关图。结果表明,在一定KC数的范围内,横向力对总力的影响不应忽略;速度力系数C_d、惯性力系数C_m及合力系数C_l与重新定义的KC数有着良好的相关性。

| Abstract: | Based on linear ware theory, the lift force on cylinder by the action of both regular waves and currents related to inline force as well as resultant force has been investigated. The relationship of the hydrodynamic coefficients of resultant force Cf, of drag force Cd, of inertia force Cm as well as of lift force CL with the redefined KC number is reported. It is indicated that in certain region of KC number, the influence of lift force on resultant force can not be ignored. |
