摘 要: 目前计算附加质量的方法并不多,特别是复杂构型物体的附加质量。使用两种不同的计算方法得到六自由度运动情况下的附加质量:一种是运用Fluent计算软件,利用Fluent动网格技术使物体作震荡运动求出物体的受力,再通过一定转化得到物体的附加质量;另一种是使用Gambit软件和面元法程序来计算物体的附加质量。给出了两种不同方法的计算结果,并且和文献结果、理论值进行了比较,证明此两种方法结果均具有较高精度。最后给出使用此两种方法计算复杂构型穿梭潜器附加质量的结果。
关 键 词: 流体力学;数值计算;复杂构型;附加质量;Fluent软件

Abstract: At present, the methods for computing the added mass of complicated objects are not too much. The added mass of a moving body is analyzed based on different techniques in this paper. Two methods are utilized to investigate the added mass of a body with six degrees of freedom when moving. One method is to calculate the forces of body vibrating in the unbounded fluid through the technique of dynamic mesh of software Fluent, and then the added mass is obtained through some transformations. Another method is to use the panel element method together with software Gambit to get the added mass based on potential flow theory. The results are presented and compared with the experiment results. The added mass of underwater vehicle with complex configuration is provided using these two techniques.
Key words: fluid mechanics; numerical simulation; complex configuration; added mass; Fluent software
