Harmonic Maps and Ideal Fluid Flows

Aleman, Alexandru LU and Constantin, A. (2012) In Archive for Rational Mechanics and Analysis 204(2). p.479-513
Abstract
Using harmonic maps we provide an approach towards obtaining explicit solutions to the incompressible two-dimensional Euler equations. More precisely, the problem of finding all solutions which in Lagrangian variables (describing the particle paths of the flow) present a labelling by harmonic functions is reduced to solving an explicit nonlinear differential system in C-n with n = 3 or n = 4. While the general solution is not available in explicit form, structural properties of the system permit us to identify several families of explicit solutions.
