Development and separation of inner bound layer of hydraulic coupler vane and vortex diffusion are controlled by means of the method of hole drilling on the vane to raise torque coefficient of the coupler. 采用在液力偶合器叶片上打孔的方法,控制其内部附面层的发展、分离和旋涡的扩散,以提高偶合器的力矩系数。
Based on the analysis of linear wave making theory, the velocity potential and free surface wave profile were formulated for a 3 D bound vortex translating under the near free surface. The required numerical methods were implemented and the example computations were carried out. 基于段涡的线性兴波理论分析,给出了段涡的线性兴波速度势和自由表面波形的计算公式,提供了数值计算方法并且给出了相应的数值计算结果。
