A Desingularized Isolated Source Method for Potential Flow Problem Wu Jingping Zou Zaojian Wang RenkangThis paper describes a desingularized isolated source method for potential flow calculation. The boundary surface is expressed by NURBS, and the isolated sources are distributed outside of the flow field. Numerical calculations were performed for the flow around a sphere in the infinite flow field. The numerical results were compared with the analysis solution, which have shown the high accuracy and efficiency of the proposed method.potential theory; boundary panel method; desingularized source; Rankine source
