Abstract
The results of numerical study of the interaction of supersonic molecular nitrogen flow with a normal glow discharge in a magnetic field at velocities M = 2 and 5 and a pressure of 0.6 Torr are given. It is shown that, depending on the polarization of the magnetic field induction vector, the magnetic field can both accelerate and slow down the motion of the discharge current column in gas flow. When there is no magnetic field, the normal glow discharge is not carried away by the flow, but moves at a noticeably lower velocity. This is a consequence of the influence of the gas boundary layers near the surfaces and a delay in the rate of ionization processes in the electric current column of gas-discharge plasma relative to the velocity of motion of the neutral gas that penetrates the discharge.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
