The effect of viscosity on the wave resistance experienced by a
two-dimensional perturbation moving at uniform velocity over the
free surface of a fluid is investigated. The analysis is based on
Rayleigh's linearized theory of capillary-gravity waves. It is shown in
particular that
the wave resistance remains bounded as the velocity of the
perturbation approaches the minimum phase speed (ρ is the liquid density, γ is
the liquid-air surface tension, and g the acceleration due to
gravity), unlike what is predicted by the inviscid theory.
