Abstract
In basic design of offshore or onshore structures, prediction of surface waves due to uniform motion of the floating body is essential to achieve an optimum body shape. Whereas, in the practical hydrodynamics, using of towing tanks is common and so cost and time consuming to conduct it, so a reliable numerical tank is interesting. A wide channel with constant depth constitutescomputational domain. It assumes that fluid is incompressible and non-viscous and the flow is irrotational. Therefore, Laplace’s equation could describe flow field.3D Boundary Element method based on second Green’s Identityis implemented to solveLaplace’s equation. Impermeable boundary condition is satisfied by Image method and Cauchy integral theorem and Poisson summation formula is used to determine Principle value integral. In this study, numerical simulation is conducted for a hemisphere and added mass and generated wave profile is presented.
