Wave Resistance of a Full Ship in Medium Speed

抄録

The Wave resistance of cargo ships of a high block coefficient is calculated by the low speed theory in low and medium speed range. The nonlinearity of the free surface condition is ascertained to exert great influence upon the wave resistance, and the results calculated by the low speed theory coincide fairly well with the measured results, although the waves generated by the afterbodies are entirely neglected. The wave resistance of full ships, however, can not always be predicted with good accuracy by the low speed theory. Therefore, the boundary value problem is scrutinized by making use of Green's function, and some comments on the improvement of the low speed theory are mentioned.
