| 摘 要： | 在ＫＣ为４０～３５，雷诺数Ｒｅ为６×１０３～２×１０４参数范围内就规则波作用下垂直圆柱局部波浪力进行了实验研究．给出横向力随ＫＣ数类型变化的划分．基于Ｓｔｏｋｅｓ二阶波理论和Ｍｏｒｉｓｏｎ公式得到圆柱阻力系数ＣＤ，惯性力系数ＣＭ和最大升力系数ＣＬｍａｘ沿桩柱的分布及其随ＫＣ数的变化规律．结果表明，在波表面间歇区的桩柱的局部水动力系数变化显著，越向波峰位水动力系数ＣＤ和ＣＬｍａｘ越减小，而ＣＭ值却越增高．

| Abstract: | The local wave forces acting on vertical circular cylinder in regular waves have been investigated experimentally under the condition that the K C number were in the range 4 0 to 35 and the Reynolds numbers 6× 10 3 to 2× 10 4 . Based on Morison equation and the second-order Stokes wave theory, the local drag, inertia and the maximum lift coefficients: C D, C M and C L max along the cylinder are computed. It hase been found that the C D, C M and C L max values very ... |
