Steady Water Waves: Theory and Computation
Abstract: Consider a classical 2D gravity wave with an arbitrary
vorticity function. Assume such a wave is traveling at a constant speed
over a flat bed. Onecan prove that there exist families of such waves of
large amplitude. I will discuss the existence proof and also exhibit
some recent numerical computations. If the vorticity is sufficiently
large, the first stagnation point occurs not at the crest (as with
irrotational flows) but on the bed directly below the crest. For
variable vorticity there can also be stagnation points in the interior
of the fluid.
