AN INVESTIGATION OF THE FLUID FLOW ABOUT SHIPS

The principal purpose of this research has been to assess the accuracy and utility of the surface-source distribution method for computing the inviscid-fluid flow around a ship's hull. Comparisons of computed and measured pressure distributions indicate that the surface-source distribution method works quite well for fine hulls. Increasing the number of sources distributed on each side of the hull beyond 100 sources has little effect on the computed results. On the fine hulls tested the presence of the boundary layer or the fact that the model is free to sink and trim does not affect the pressure distribution in a significant way.
