Wave force on the submerged inclined thin plate in intermediate depth of water

摘要

The paper presented is a solution of wave force,using small amplitude,linear wave theory on two-dimensional inclined submerged rectangular thin plates.The solution method is confined in a finite domain,which contains both the region of different depth of water and the plate.In this paper,analytical solution is derived and the result is validated with numerical results.Simpson’s 1/3 rule is used here for the validation.The variations of horizontal and vertical wave forces on the plate with respect to the wave amplitudes are obtained in the intermediate depth of water and at a different plate angle.It is observed that the wave forces on the plate are high at the free surface for d/L = 0.24 compare to the other relative depth.It is also observed that the wave forces of the two types of plate are gradually converging with the decreasing value of the relative depth.Laplace’s equation and boundary value problems are solved in a finite domain,by the method of separation of variables and the small amplitude linear wave theory.
