Abstract EN
We consider the stability problem of inviscid compressible axial flows with axial magnetic fields following the work of Dandapat and Gupta (Quarterly of Applied Mathematics, 1975).
A numerical study of the stability of some basic flows has been carried out and it is found that an increase in the magnetic field strength has a stabilizing effect on subsonic flows and a destabilizing effect on supersonic flows.
An analytical study of the stability problem has also been done in the present paper, but this analytical study is restricted by the approximation M≪1 and ci≪1, where M is the Mach number and ci is the imaginary part of the complex phase velocity c.
A semicircular region depending on the magnetic field parameter and the Mach number is found for subsonic disturbances and as a consequence it is found that sufficiently strong magnetic field stabilizes all subsonic disturbances.
Under a weak magnetic field, it is shown that short subsonic disturbances are stable.
