Numerical Calculation of Second-Order Wave Resistance,
Abstract
The wave resistance due to the steady motion of a ship was formulated in Lagrangian coordinates by Wehausen (16). By introduction of an iteration scheme the solutions for the first order and second order were obtained. The draft/length ratio 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 wave resistance does show better agreement with measured wave resistance than the first-order theory does. However, the agreement is still not good enough so that computation can replace experiment, and indeed in certain cases the computed values show physically unacceptable behavior.
