Abstract
The ability of the panel methods in solving the potential flow problem around 2-D lifting airfoils is tested in this study. The approximate solutions for potential flow pasts thick, thin, symmetrical, and non-symmetrical airfoils have been calculated by using panel methods and then compared with either the exact analytical solution or the numerical solution obtained by using a perturbation method. As a results, the linear-varying strength vortex method is seemed to be the better one in precision in solving the all four problems.
