摘　　要：运用数值求解不可压缩雷诺平均N-S方程的方法研究了带鳍舵无动力鱼雷的流体动力特性。研究表明,本文所采用的Menter两方程SSTκ-ω湍流模型求解雷诺平均N-S方程的数值计算方法,可较为细致的模拟鱼雷周围的定常绕流特性,并对流体动力特性给出合理的流动机理解释。鳍舵对雷体的升力和俯仰特性有显著提高,具有良好的操纵控制能力。In this paper, the fluid dynamic characteristic on the torpedo with fin and rudder was researched by solving incompressible Reynolds Average N-S equation numerically. The study indicated that the method solving RANS equations closed by SSTk-ω turbulence model was suitable to simulate the fluid field around the torpedo in detail. The paper explained the fluid proved and a good control mechanism for fluid dynamic characteristic of the torpedo. The lift and pitching moment is imcapab and a good control capability is provided for the torpedo by fin and rudder.
