| 摘 要： | 运用基于速度势的低阶边界积分方法研究了二维水翼的定常局部空化。通过迭代求解给定了空化数的空泡长度和空泡形状,运动学和动力学边界条件在迭代过程中满足;采用回射流模型和压力恢复闭合模型代替空泡后的高湍流度的二相尾流。计算结果和已发表的数值结果进行了比较。

| Abstract: | The steady partially cavitating flow around two-dimensional hydrofoils was simulated numerically by the low-order potential-based boundary integration method.The caviy shape and length are determined for given cavitating numbers in the course of iteration by satisfying the kinematic and dynamic boundary conditions.The re-entrant jet model and the pressure-recovery close model are adopted to replace the high turbulent and two-phase wake forming behind the cavity.The results are compared with the other published numerical ones. |
