摘要
以三体船操纵性能预报为目的 ,采用势流理论三维面元法对相对较难计算的三体船旋转水动力进行了计算.根据涡元法在船体表面和尾涡面布置均匀涡格,使涡格强度满足边界条件和尾缘库塔条件,进而求解船体表面附着流场分布,并依此计算出船舶所受水动力.通过算例验证了该算法的正确性和适用性,并得出了侧体布局对三体船操纵性旋转水动力影响极大的结论.
Abstract
In order to predict the manoeuverability of trimaran ,the relatively difficult rotary hydrody-namics of trimaran is calculated by using the three-dimensional panel method of potential flow .Ac-cording to the method of vortex element ,the disturbing velocity of hull surface is solved with the help of hull surface condition and Kutta condition when even vortex loops are distributed on the hull sur-face and the wake vortex surface .Then the force on the trimaran hull is also obtained .Finally ,the va-lidity and applicability of the model are verified by numerical simulations and the outrigger arrange-ment influence on rotary hydrodynamics of trimaran is proven to be great .
