水下运动物体间相互作用力的计算探讨

本文首先用体内奇点分布法建立了水下多个运动回转体的数学模型,基此提出了一种新的计算多物体相互作用力的方法──等价拓展体法,达到考虑粘性、简化边界层计算的目的。以上方法都以两个运动回转体为例作了数值计算与比较。

THE COMPUTATION OF INTERACTION FORCES BETWEEN UNDERWATER MOVING BODIES

in this paper,the singularity distribution method is applied to establishing mathematical model of multiple underwater bodies of revolution. Based on this model,a new computing method-"equivalent extending body method"-is proposed for computing interaction forces between multiple bodies,the viscous effects may be considered in future to simplify the computation of boundary layer. Two moving bodies of revolution are used to compute interaction forces by these methods and the results are compared. It shows that the new method is effective.
