The Kochin function [math]\displaystyle{ \mathbf{H}(\tau) }[/math] is given by
where [math]\displaystyle{ \delta/\delta n }[/math] is the inward normal derivative, [math]\displaystyle{ \phi }[/math] is the velocity potential and [math]\displaystyle{ \Gamma_s }[/math] is the wetted body surface.
Many physical parameters, such as the Scattered Wave in Three-Dimensions, the Radiated Energy in Three-Dimensions, and the Wave Forces in Three-Dimensions can be calculated from the Kochin Function.
