NUMERICAL EVALUATION OF A WAVE-RESISTANCE THEORY FOR SLOW SHIPS

A procedure is presented for the numerical calculation of wave resistance of conventional ship forms. Wave resistance theory used in this calculation takes into account the nonlinear effect on the free surface condition. Because of this a remarkable attenuation of the humps and hollows of the wave resistance curve is attained in the practical speed range of conventional commerical ships. Taking a semisubmerged sphere as an example, each stage of numerical calculations is examined by comparing it with the analytical values. Finally, wave resistance of conventional ship forms is calculated and compared with experimental values. Within a practically acceptable order of magnitude wave resistance can be estimated by this theory.
