A numerical method of solution for the Kelvin-Neumann problem

A numerical procedure is described for the steady, inviscid flow of a moving disturbance at the free surface. The method is valid for application in the case of a moving pressure distribution at the free surface. The solution is obtained by collocation where Laplace's equation is transformed into a system of differential equations. In the diagonal dominant structure one equation can be distinguished of the hyperbolic type and the other equations of the elliptic type.
