Abstract
This paper concerns the uniqueness of the solution to the 2D steady Navier–Stokes equations in an infinitely long convergent channel. In Landau and Lifschitz’s book (Landau and Lifschitz, 1987), they obtained an exact solution. We call it the Landau–Lifschitz solution. A natural question is whether the Landau–Lifschitz solution is a unique solution. This paper tries to answer this question.
期刊介绍:
Physica D (Nonlinear Phenomena) publishes research and review articles reporting on experimental and theoretical works, techniques and ideas that advance the understanding of nonlinear phenomena. Topics encompass wave motion in physical, chemical and biological systems; physical or biological phenomena governed by nonlinear field equations, including hydrodynamics and turbulence; pattern formation and cooperative phenomena; instability, bifurcations, chaos, and space-time disorder; integrable/Hamiltonian systems; asymptotic analysis and, more generally, mathematical methods for nonlinear systems.
