Moment of Wave Energy Model in Water of Finite Depth

In this work, we have consider a particular wave energy device to create electrical energy in water. The device contains a submerged cylindrical obstacle placed above a plate which is also assume as a cylindrical structure. Also the diffracted potentials are derived by applying several mathematical model for each region of the fluid. Due to continuous flow of the fluid, we have introduce a system of equation for some unknown constants which are involve in potentials expression. Finally, we derived moment of the device due to diffraction wave field and present graphically.
