本文提出了适用于任何翼型叶栅二元定常超空泡绕流求解的理论和方法,并对平板叶栅作了数值计算,得出在不同空泡数下升力,阻力、出流速度大小及方向和自由流线的形状。数值试验表明,采用本文所提出的方法求解超空泡叶栅绕流问题是有效的。 In this paper, the theory and method for the solution of the bimodal constant supercavity flow around any airfoil cascade are proposed, and the numerical calculation of the plate cascade is carried out. The results show that the lift, drag and outflow velocity And the direction and the shape of the free streamline. Numerical experiments show that it is effective to solve the problem of flow around the supercavity cascades by the method proposed in this paper.
