VISCOSITY, WAKE, AND SHIP WAVES

In this paper a theory of the effect of viscosity on ship waves is presented. It is shown that the wake affects the singularities kinematically equivalent to the hull and generates waves which modify the resulting wave pattern. The theory may explain why the estimate of the viscous resistance obtained by means of a wake survey and the estimate of the wavemaking resistance obtained by means of a wave analysis do not add up, in general, to the total resistance measured by using a dynamometer. The discrepancy seems to be due essentially to the existence of a wavemaking viscous resistance.
