Abstract:
Wave survey tests, according to the XY method, were carried out in the Webb Towing Tank on an optimum ship form model. This method utilizes measurements of the force due to the waves impinging on a long vertical cylinder to deduce the wave resistance directly from the model wave pattern. The form tested was one of a series optimized by computer at the University of California with respect to total drag, assuming equivalent flat plate friction and the linearized Michell theory of wave resistance, at a certain design Froude number. The experimental results show the wave resistance to be small in the vicinity of the design Froude number and demonstrate a decided advantage of such direct wave survey methods over the classical Froude method of determining the wave resistance in such cases.
