THE DISTRIBUTION OF SINGULARITIES KINEMATICALLY EQUIVALENT TO A MOVING HULL IN THE PRESENCE OF A FREE SURFACE

This paper is an analysis of the properties of different singularities distributed over the surface of a partially immersed hull. The wave field associated with these distributions is characterized by a function H, which identifies with Kochin's function only when the hull is completely immersed. The coefficient of wave resistance associated with the modified Kochin's function H cancels out as F to the 6 power when the Froude number F goes to zero, and that happens whatever the nature of the singularities distributed over a partially immersed hull.
