| 摘 要： | 采用球形体积方法对时域螺旋桨空泡噪声进行了数值计算,并与另外2种方法进行了比较。首先提出单极子模型计算螺旋桨空泡噪声的可行性;其次应用面元法计算出满足螺旋桨水动力学条件以及空泡动力学条件的螺旋桨空泡形状;最后结合Lighthill方程在特殊情况下的解将空泡体积脉动转换为螺旋桨空泡噪声。

| Abstract: | The propeller cavitation noise in time-domain has been gained by bubble volume pulse method.Calculated results have been compared with those results obtained by other two methods.First,the availability of monopole theory to predict propeller cavitation noise was validated.Second,bubble volume pulse of propeller-blade has been computed by surface panel method which satisfied propeller hydrodynamics and cavitation kinetics condition.Then Propeller cavitation noise has been gained by using Lighthill equation to transform propeller bubble volume pulse. |
