摘　　要：文章以SUBOFF潜艇模型为研究对象,对附体相对主艇体处于不同位置下的尾流场进行了数值模拟计算。采用k-w湍流模型,求解RANS方程得到附体处于不同布置位置下的尾流场分布,计算结果以桨盘面不同半径处的轴向无量纲速度和不均匀度系数给出。通过对计算结果的比较,分析了附体的布置位置对潜艇尾流场的影响。The flow field of the submarine model SUBOFF is numerically simulated when different position of the appendages is performed. By solving RANS equations with turbulence models, the distribution of the astern flow field is carried out and the calculation results are given out in the form of non-dimensional speed at different radius on the propeller disk and the non-uniform coefficient. The comparison between the results tells us how the layout changes of appendages influence the flow field of the submarine model.
