| 摘 要： | 提出了确定带自然空泡运动物体附加质量的方法.这一方法基于在数值水洞中作摇荡运动物体的水动力计算, 包括两个主要步骤:首先采用CFD技术模拟空泡流场,求解水动力;然后根据物体运动方程,由水动力计算出附加质量.研究了带自然空泡圆盘和轴对称细长体的附加质量.计算结果与理论解一致,验证了本文方法的有效性.与切片法相比,本文方法可以更为准确地定量预报带空泡运动轴对称细长体的附加质量.

| Abstract: | A method to determine the added mass of running vehicle with cavitation is proposed based on calculating hydrodynamic forces of the vehicle swaying or rolling in numerical tunnel. It includes two main steps. The cavitating flow is simulated with CFD technique to solve for hydrodynamic forces of the vehicle first. Then according to the equation of motion, the added mass is deduced from the hydrodynamic forces. To validate the present method, the added mass of a cavitating moving disk and a cavitating axisymmetric slender body are investigated. The numerical results are consistept with the analytical solutions. The present method can predict the added mass can be more accurate than the strip method. |
