The paper “A new equation describing travelling water waves“, co-authored by Katie Oliveras and Vishal Vasan, has been published in the Journal of Fluid Mechanics. In the paper, a new single equation for the surface elevation of a travelling water wave in an incompressible, inviscid, irrotational fluid is derived. The equation is derived without approximation from Euler’s equations, valid for both a one- and two-dimensional travelling-wave surface. The new formulation can be used to efficiently derive higher-order Stokes-wave approximations. The paper can be found here.
