WebAug 1, 2024 · To generate a high order panel that models this boundary, we need to select a baseline along which the panel is parameterized. Since only the direction of this reference line will be of importance, we let it start at z1 with some angle θ pointing in the general direction of z2, see Fig. 2.1. WebThe program performs a potential flow analysis using a higher order panel method, in which the vorticity varies linearly along each panel representing the airfoil. Then, an integral boundary layer method is applied, using a separate boundary layer analysis module. Beginning at the stagnation point, the method solves the boundary layer equations. bisexual football
