The solution for the finite free flooding cylinder is built up from the solution for a ring on an infinite rigid baffle. The velocity in the field at the ends of the cylinder is the solution of an integral equation which was originally derived by Junger. A computer program has been developed for solving this integral equation and for obtaining the radiation impedance of the cylinder. It is found that the velocity near the ends of the cylinder is highly attenuated within 18 wave length away from the ends. Just at the ends the velocity changes radically but this violent changing stops at less than 14 wave length from the ends of the cylinder, at which point a regular attenuated sine wave starts. Author
