ANALYSIS OF THREE-DIMENSIONAL POTENTIAL FLOW AROUND A SHIP HULL

The method of singularities is applied for the solution of three-dimensional potential flow around arbitrarily shaped bodies. The three-dimensional bodies are represented by systems of singular functions with singularities placed inside the body. An optimization procedure was applied to determine the optimal locations of the singular functions. A rigorous treatment of the problem is presented to establish the validity of the mathematical formulation and the optimization procedure. The method developed here can be applied for analyzing flow around obstacles for which the singularities at the boundaries could not be treated efficiently using presently used techniques. Presented are computational considerations and numerical results showing the velocity distribution around a regularly shaped obstacle and for the bow of an icebreaker.
