摘　　要：通过数值计算方法,模拟回转体在水下的航行,分析回转体周围流场、压强及其壁面上阻力的分布,并根据计算结果为该回转体设计了有效的微气泡减阻方案。The resistance feature of the revolving object moving underwater was simulated numerically. The flow field surrounding the revolving object, pressure and resistance distribution on its wall were calculated in order to design a micro-bubble reducing resistance scheme for the revolving object.

关 键 词：回转体 微气泡 摩擦阻力 粘压阻力
