A METHOD OF COMPUTING NONLINEAR WAVE RESISTANCE OF THIN SHIPS BY COORDINATE STRAINING

A systematical procedure is derived for determining the distribution of source along the centerplane of a thin ship which generate a flow (and the associated wave resistance) satisfying the free-surface and body boundary conditions at second order. The method relies on a mapping of the flow domain on to a new domain by slightly straining the coordinates. The horizontal straining is selected such that the nonlinear solution should be easily derived from the first-order (Michell) solution in the strained domain. The results are shown to be similar to those obtained by Guilloton's method, but new features, such as the forward displacement of the bow singularities, are present.
