| Abstract: | The boundary element method for two dimensional incompressible potential flow around the isolated airfoil is analysed in the paper. When control equations and boundary conditions are numerically discretized, the kutta-condition is led into the control equations, and then the new discrete. boundary integral equations are derived. These equations are first order linear ones and can be solved directly. The potential flow around the cylinders with and without circulation as well as the isolated airfoil NACA 0018 are studied numerically in the paper. Results have shown that the present procedure is rather accurate, reliable and simple. Application of the present procedure can save the storage of the computer and decrease the computational time. |
