WAVES GENERATED BY MODEL SHIP HULL

A literature survey of theoretical and experimental investigations for the configuration of the wave pattern and characteristics of the individual wave phases for waves generated by a moving ship is presented. This discussion is primarily concerned with the procedures and results of a qualitative and quantitative experimental investigation of the characteristics of surface waves generated by a model ship hull of basic form, as a function of ship speed and distance from the sailing line in deep and shallow water. Stereophotogrammetry and standard resistance-type parallel-wire gages were employed in the measurement of the waves generated by the model. Based on this study (including comparison with theory), the author concludes that although existing theory on ship generated waves provides a general indication of the wave patterns to be expected, more precise predictions of diverging and transverse wave amplitudes, cross-section and crest-line patterns, and the decrease in amplitude with distance from the sailing line can be obtained only through ship hull model and prototype studies. The author's recommendations for extending this study to provide comprehensive data for design purposes are included.
