A METHOD FOR ACCURATE FORCE CALCULATIONS IN POTENTIAL FLOW

Instead of superimposing distributed singularities like source and dipole panels, point sources are used to satisfy exactly the body boundary condition of no flux through polygonal surface patches, instead of fulfilling the boundary condition at discrete points only. Having determined the source strengths from the boundary condition, the average velocity on a triangular surface patch follows from the potential at the patch vertices. Together with the local velocities at the patch vertices, the pressure integral over each triangle can be approximated. The second-order convergence of pressure forces with decreasing panel length and the high accuracy compared to other methods using the same panel number and computer time is demonstrated for a sphere and for the HSVA tanker.
