NONLINEAR HYDRODYNAMIC FORCES ACTING ON TWO DIMENSIONAL BODIES (1ST REPORT, DIFFRACTION PROBLEM)
A new method which simplifies the calculation of higher-order hydordynamic forces is proposed. Solving the integral equation on boundary surfaces including the free-surface by this method, the non-linear terms on free-surface may be directly computed. Making use of this method, the diffraction potentials are calculated up to the second-order terms in two-dimensional problems. Results obtained are as follows: (1) The numerical results by the method agree well with existing results in radiation and diffraction linear problems. (2) Second-order diffraction forces due to non-linear free-surface boundary condition is nearly proportional to the wave-number of incident wave. (3) Total second-order diffraction forces computed by the method show good coincidence with the experimental results.
