| 摘 要： | 本文用奇点法解厚翼剖面局部空泡绕流问题。求解时精确考虑了空泡表面是一条流线的运动学边界条件,空泡表面压力为常数的动力学边界条件,以及水翼湿表面是一条流线的运动学边界条件,用迭代法求出了空泡表面的形状、压力分布等水动力特性,并与实验结果作了比较,得较好结果。

| Abstract: | Partially cavitating flow passing foil section is explored using surface singularity method. The following boundary conditions, are accurately satisfied:a. kinematic boundary condition for cavity, i. e., cavity surface is a streamline;b. dynamic boundary condition for cavity, i. e., the pressure on cavity surface is constant andc. kinematic boundary condition for wetted foil section surface, i. e. wetted foil section is a streamline.An iterative procedure is used to determine hydrodynamic characteristies including cavity shape, pressure distribution and so on.Numerical calculations for a NACA16-0.15 foil section have been carried out. Agreement between calculated results and experimental data is acceptable. |
