WAVE BREAKING RESISTANCE OF SHIPS

This paper deals with experimental and theoretical studies on breaking waves observed on the free surface around conventional ships. Experimental studies on the structure of breaking of bow waves are reviewed first, and then some results of quantitative determination of a resistance component due to breaking waves are reviewed together with studies of the effect of the protruding bulb on the wave breaking resistance. Based on the above experimental studies, a flow model is introduced, in which a thin free surface layer is superposed on a nonuniform flow induced by the double model velocity potential. It is then suggested that shortening and steepening of the surface layer waves riding on the steep local waves are considered to be a cause of wave breaking. Finally, regarding the breaking of stern waves, a theoretical study is carried out.
