3D Green Function of Oscillating Body with Forward Speed on Water of Finite Depth

Abstract

The dispersion relation of the elementary waves in the 3D Green function of oscillating body with forward speed on water of finite depth is discussed. There is a new finding with respect to the phase velocity of the elementary waves, which accompanies some modifications of the Green function. Furthermore, the possibility of the representation of the above Green function in Bessho's way is discussed from the view-point of the characteristics of the singularities in the Green function.
