Wave force on a large scale structure under the effects of current
Abstract
A numerical model is developed to calculate wave force on a large scale structure under the effects of current in waters of constant depth. With the fluid in wave-current coexisting field assumed incompressible and inviscid, and the flow irrotational, the flow motion can be described by a velocity potential. The velocity potential is separated into a steady current potential and an unsteady wave potential. The steady current potential can be expressed as a sum of a uniform current and a steady disturbance due to the presence of the structure. The surface vorticity method is employed to calculate the current velocity distribution on the structure, and for calculating the wave velocity potential including flow and structure effects, boundary element method is used. Results from these two numerical schemes are then combined to calculate wave force on the structure with the use of integrating the Bernoulli equation on the structure surface.
