摘要:低速不可压绕流中,头部形状明显影响鱼雷或UUV的流体动力特性。针对头部平端面上装设小整流锥的钝头形状雷体,采用Fluent流体分析软件,数值模拟雷体低速绕流流场特性。在0°~5°迎角范围内计算获得雷体压强分布和速度分布及运动阻力和升力系数,讨论分析结果并给出了详细模拟计算过程。

Abstract:In the low speed incompressible flow, the head shape influences hydrodynamic characteristic of torpedo or UUV. Aiming at the blunt head shape UUV mine body with a small commutating cone on the flat head end face, based on fluid analysis software Fluent, low-speed flow field characteristics of the UUV main body is computed. In 0° ~ 5° angle of attack range, distributions of the flow pressure and velocity and coefficients of the moving drag and lift are obtained. Analyzing and discussing the computing results, the calculating simulation process is described with detail. 
Key words:UUV main body;head commutating cone;Fluent;flow characteristic;force coefficients
