✦ Synopsis

In this paper, a novel high order panel method based on doublet distribution and Gaussian quadrature was adopted to deal with the potential flow problem. In the geometry representation we employed both the exact surface and NURBS surface form to construct the surface panel. These data were calculated directly from the mathematical shape definition. Furthermore, no fixed order of doublet density distribution was assumed on each panel. Not only the number of panels could be chosen, but also the Gaussian order of each panel. The numerical results for sphere, ellipsoid and Wigley hull demonstrated here indicated that the present method was adapted to the potential flow problem. Moreover, the NURBS surface geometry representation was capable of further potential flow optimal calculation.
