Abstract
The report gives a general review of various methods to study the slamming loads on ship sections. The ship sections may have a flat, or a wedge-shaped bottom. Two types of flows, namely compressible air flow and incompressible water flow, have been studied. For a flat bottom body or a wedge with small deadrise angle, the air flow has to be taken into consideration. Two methods are presented for the flat bottom body, the Method of Characteristics and the Flux-Vector Splitting Method. For wedge-shaped bodies, four available hydrodynamic methods are reviewed and introduced, including the Green Function Method, the Cauchy Integral Method, the Volume of Fluid Method, and the Conformal Mapping Method. Analysis and comments on each method are also provided together with the available numerical and experimental results. Each method has also been evaluated in this report.
