A row of counter-rotating vortices. (English) Zbl 0778.76022
Summary: In 1967, {\it J. T. Stuart} [J. Fluid Mech. 29, 417-440 (1967; Zbl 0152.454)] found an exact nonliner solution of the inviscid, incompressible two-dimensional Navier-Stokes equations, representing an infinite row of identical vortices which are now known as Stuart vortices. In this paper, the corresponding result for an infinite row of counter-rotating vortices, i.e., a row of vortices of alternating sign, is presented. While for Stuart’s solution, the streamfunction satisfied Liouville’s equation, the streamfunction presented here satisfies the sinh-Gordon equation. The connection with Stuart’s solution is discussed.
