------------------------- provides an elegant methodology to solve a class oroaw past arbitrarily shaped bodies in both two and three dimensions. The basic idea is to discrctize the body in tcnns ofa singularity distribution on the body surface, to satisfy the necessary boundary conditions, and to find the resulting distribution of singularity on the surface, thus obtain fluid dynamic properties orthe flow [IO}. Nowadays, engineers arc seeking ever faster ways to design propellers for customers' requirements and enhancing speed to market. The lifting line method and panel method arc very useful and commonly used to design conventional propellers. The required input data for lifting line method and panel method is shown in table I.
