Stokes drift[edit]

Will you please provide your implementation details (of the plotted equations) when you created the OGV animation related to Stokes wave with drift? I am trying to clarify a doubt: the drift velocity does not appear in the expression of the free surface elevation (to fix ideas, say a second-order approximation). However in the expressions for the particle trajectories we have an explicit term that corresponds to the drift velocity.

The confusing part is this: The free surface height obtained by solving the asymptotic sequence of the potential flow equations gradually separate (with the drift velocity) from the free surface tracked by the particle trajectories.

However, in the OGV animation you posted/created no such phase errors occur. Will you please share the equations that you plotted to create this OGV image? — Preceding unsigned comment added by Nadukandi (talkcontribs) 14:00, 13 April 2015‎ (UTC)

Please see the description page of the animation at Commons, for the computational techniques used to obtain the flow associated with the wave motion. Best regards, Crowsnest (talk) 11:30, 16 April 2015 (UTC)
