| Abstract: | The diffraction of waves in linear theory around multiple vertical cylinders is solved numerically by the boundary element method. A fundamental solution is adopted considering the satisfaction of boundary conditions on the free surf- ace as well as the radiation condition at infinity. Consequently, the number of variables involved is reduced to a great extent. The paper analyzes the effect of spacing of cylinders to the wave force acting on the bodies. In addition, results corresponding to single cylinder and twin or four cylinders are enclosed. The present method is available for the analysis of wave loading on multiple cylin- ders of any section with constant area. |
