NUMERICAL CALCULATION OF SECOND-ORDER WAVE RESISTANCE

The wave resistance due to the steady motion of a ship was formulated in Lagrangian coordinates by Wehausen. By introduction of an iteration scheme the solutions for the first order and second order were obtained. The draft-length ration was assumed small in order to simplify numerical computation. In this work Wehausen's formulas are used to compute the resistance numerically. A few models are selected and the wave resistance is calculated. These results are compared with other methods and experiments. Generally speaking, the second-order resistance shows better agreement with experiment than first-order theory in only a restricted range of Froude number, say 0.25 to 0.35, and even here not uniformly. For larger Froude numbers it underestimates seriously.
