摘要
基于势流理论和边界元方法,对水下运动的回转体的空泡流进行了数值模拟.将半经验空泡封闭模型由平面流动推广至轴对称流动.对头部为圆锥的圆柱体空泡流动进行了数值计算.分析了空化数、半锥角、空泡长度间的关系.计算与实验结果符合较好.
Axisymmetric cavitating flows around the cone-capped cylinder are numerically simulated with the boundary element method under potential flow assumption. The relationship between the cavity number, cavity length, cavity thickness and cone angle is analyzed. Computing results agree with experimental ones.
