Steady super-Alfvénic MHD shocks with aligned fields in two-dimensional almost flat nozzles

Shangkun Weng, Wengang Yang

The Lorentz force induced by the magnetic field in MHD flow introduces a fundamental difference from pure gas dynamics by facilitating the anisotropic propagation of small disturba…

On three dimensional steady super-Alfvénic magnetohydrodynamics shocks with aligned fields

Shangkun Weng, Wengang Yang

The coupled motion between the hydrodynamic flow and magnetic field introduces significant complexity into the structure of the magnetohydrodynamic (MHD) equations. A key factor co…

The steady inviscid compressible self-similar flows and the stability analysis

Shangkun Weng, Hongwei Yuan

We investigate the steady inviscid compressible self-similar flows which depends only on the polar angle in spherical coordinates. It is shown that besides the purely supersonic an…

Some three dimensional smooth transonic flows for the steady Euler equations with an external force

Shangkun Weng, Zhouping Xin

We establish the existence and uniqueness of some smooth accelerating transonic flows governed by the three dimensional steady compressible Euler equations with an external force i…
