題目: Pressure and Particle Trajectories beneath a Stokes Wave

概要: Consider periodic two-dimensional gravity
water waves propagating in irrotational flow at
constant speed at the surface of water with a flat bed.
Then the pressure in the fluid strictly decreases horizontally
away from the crest line and strictly increases with depth.
Moreover, along each streamline the horizontal velocity
strictly decreases away from the crest line. Some particle
trajectories are closed orbits but most are looping orbits
that drift either to the right or the left, depending
on the presence of an underlying favorable or adverse current.
These results have been obtained as joint work with Walter
Strauss.
