Numerical analysis of the wave force acting on a cylinder in regular waves using the MPS method

Abstract

We simulated the interactions between a second-order Stokes wave and vertical circular cylinder in a three-dimensional numerical wave tank using the moving particle semi-implicit method. The numerical wave tank was modified to generate a series of Stokes waves. Fluid–structure interactions were simulated under the same wave conditions as the model experiments. We compared the hydrodynamic coefficients obtained by the simulations with those of the experiment to validate this method. We also simulated the wave force around a free surface using the developed method in different wave conditions.
