| Abstract: | The design of a cascade is a hot point in fluid dynamics. The steady positive problem of the cascade is studied in this paper. The objects are the wing types NACA0012 and NACA2412. At first the shapes of the wing cascades are given, and the surface velocity distribution of the projects is calculated. Then the numerical simulation of the cascades is conducted by means of the finite element method （FEM） based on a variational principle. In con- trast to the standard velocity distribution, the numerical results indicate that the present method is powerful and can be employed for practical hydrofoil design. |
