Froude-Krylov force



The Froude-Krylov force, sometimes also called the Froude-Kriloff force is a hydrodynamical force named after William Froude and Alexei Krylov. The Froude-Krylov force is the force introduced by the unsteady pressure field generated by undisturbed waves. The Froude-Krylov force is together with the diffraction force the total non-viscous forces acting on a floating body in regular waves. The diffraction force is due to the floating body disturbing the waves.

Additional recommended knowledge

The Froude-Krylov force can be calculated from:

\vec F_{FK} = - \iint_{S_w} p ~ \vec n ~ ds

Where Sw is the wetted surface, p the pressure and \vec n the body's normal vector pointing into the water.
