中文摘要：
为获得船舶风载荷系数的准确计算方法及其在不同风向角下的分布规律,以某内河船舶为研究对象,对船舶水上结构表面风场风压进行数值模拟,得到不同风向角下的风载荷系数,将计算结果与Fujiwara和Blendermann方法对比,结果表明,k-εRealizable湍流模型在计算风载荷系数时准确度较高;随着风向角变化,船舶风载荷系数变化较大;所采用的数值计算方法及网格形式可较好预报游轮风阻力。
英文摘要：
In order to obtain the accurate calculation methods of wind load coefficient and its distribution under different wind direction angle,an inland cruise ship is chosen as a research object whose wind field pressure distribution and wind load coefficients are simulated by means of computational fluid dynamics,and the numerical results are compared with those of Fujiware and Blendermann method. The results show that the model of κ-ε Realizable has a high accuracy; wind load coefficients vary greatly with the coming wind angles; and the method of numerical computation adopted in this paper can accurately calculate the wind load of the inland cruise ship.
