A selection principle for 2D steady Euler flows via the vanishing viscosity limit

Changfeng Gui, Chunjing Xie, Huan Xu

The 2D Euler system, which governs inviscid incompressible fluid flow, can admit infinitely many steady solutions in a given domain with slip boundary conditions. To select physica…

Global Uniqueness of Subsonic Flows for the Steady Euler-Poisson System

Myoungjean Bae, Ben Duan, Chunjing Xie

We prove the global uniqueness of multidimensional subsonic flows for the steady Euler--Poisson system in a bounded nozzle in the sense that uniqueness holds without restricting so…

Least total curvature solutions to steady Euler system and monotone solutions to semilinear equations in a strip

Changfeng Gui, David Ruiz, Chunjing Xie +1

This paper focuses on establishing the existence of a class of steady solutions, termed least total curvature solutions, to the incompressible Euler system in a strip. The solution…
