Title: Computation of the free surface flow around lifting and non‐lifting bodies by a mixed potential and velocity based boundary element method
Abstract: Abstract The purpose of this paper is to present a mixed potential and velocity based boundary element method to solve wave making resistance problems. In this method, the singularity strengths on a non‐lifting body or a lifting body are solved by a potential based boundary element method, and the singularity strengths on the free surface are solved by a velocity based method. The interaction between the body and the free surface is then calculated by an iterative procedure. It is found that a block iterative matrix solver can be used in the solutions, and computational time has thus been dramatically reduced. Computational results are shown for the comparison of the presented method and a source only velocity based method. Calculated results for both non‐lifting and lifting bodies are also compared with the experimental data. Key word : boundary element methodfree surfacewave making resistanceKutta condition.
