Numerical Prediction of Wave Forces on Submerged Half-Cylinders,
Abstract
The present report investigates different numerical methods of solution to compute wave forces on submerged shell type structures of arbitrary shape. Although we only dealt here with two dimensional applications, future applications will involve three dimensional analysis. Hence it is of primary importance that the technique under consideration can be extended to three dimensional applications. The report considers for comparison purpose the application of the finite element method but it is evident that the technique can not be easily extended to general three dimensional problems. Thus we concentrate in the boundary element method which is newly developed technique. The present report deals with the accurate computation of the forces on the semimerged shells and concludes that it is necessary to properly define the geometry of the obstruction. Otherwise an uneconomic number of fluid boundary elements is required to obtain accurate solutions. Higher order elements as the one advocated in this report are also necessary to maintain compatibility of shell and fluid movements.
