INTERFERENCE COEFFICIENT OF WAVE FORCES ON SMALL SCALE CYLINDERS BY USING NUMERICAL SIMULATION METHOD
Three-dimensional numerical models are developed based on 3-D unsteady Reynolds Equation, in which the standard k-ε equation is used to close the Reynolds equations and VOF method is used to reconstruct the free surface. Then the models are used to compute the wave force on single small scale cylinder, and verified by experimental data and compared with the results gained by Morison equation. Finally, in order to get the interference coefficient of wave forces on small scale cylinders, the models are used to simulate the processes of periodic wave propagation through the cylinders under the following four cases: single cylinder; two small scale cylinders arranged fore-and-aft; two small scale cylinders arranged parallel and four small scale cylinders matrix arranged. The wave surfaces, the complicated velocity fields around the cylinders and the wave force of the cylinders are also obtained. It can be found that the horizontal wave force of each cylinder is affected more intensively when the cylinders are closer.
