Title: Formation of shock waves in a discharge plasma in the presence of a magnetic field

Abstract

The effect of an external magnetic field on the dynamics of shock waves generated in an argon plasma due to both explosive processes on the cathode and expansion of the spark channel has been studied experimentally. It is shown that the expanding plasma of the cathode spot forms a shock wave and that the application of a longitudinal magnetic field decelerates the radial expansion of the cathode plasma. It is found that the intensities of some argon spectral lines increase in the presence of a magnetic field.

  • The motion of a shock wave in a gas with infinite electric conductivity in the presence of a gravitational field and in a transverse magnetic field was investigated. Since the motion of the gas outside the shock wave was considered, the viscosity and the heat conduction were neglected, but the change in the entropy was taken into account. It is shown that in the case of strong shock waves, it is more convenient to use the Lagrange method rather than the Euler method when solving the problem. By means of a series expansion, within the framework of the Lagrange method,more » an approximate solution is obtained for a gas with a constant temperature in a constant magnetic field. Simultaneously, results of a numerical solution are given and the limit of applicability of the approximate solution is indicated. It was shown that the magnetic field produced an increase in the rate of propagation and an expansion of the region of influence of the shock wave. The course of the solution of the problem by the Euler method is briefly indicated.« less
  • Classical models of magnetic reconnection consist of a small diffusion region, which is bounded by two pairs of slow shocks. In these models, the plasma is accelerated across the shocks. It has long been postulated that violation of symmetry across the current sheet will lead to the formation of intermediate waves in the current sheet. These asymmetries are important properties of space plasma current sheets. Equally important in space plasmas is the presence of sheared flow across current sheets. In this study, the structure of steady-state reconnection is investigated in the presence of a shear flow across the current sheetmore » with symmetric density and magnetic field strengths using two-dimensional magnetohydrodynamic (MHD) simulations. The results show that for sheared flow above the Alfven velocity of the inflow regions no steady-state magnetic reconnection occurs. For sheared plasma flow below this critical velocity steady-state reconnection is obtained. A detailed examination of the Rankine--Hugoniot jump conditions reveals that each pair of slow shocks is replaced by a strong intermediate shock and a weak slow shock in the presence of shear flow.« less
  • We report on the experimental observation of canard orbit and mixed mode oscillations (MMOs) in an excitable glow discharge plasma induced by an external magnetic field perturbation using a bar magnet. At a small value of magnetic field, small amplitude quasiperiodic oscillations were excited, and with the increase in the magnetic field, large amplitude oscillations were excited. Analyzing the experimental results, it seems that the magnetic field could be playing the role of noise for such nonlinear phenomena. It is observed that the noise level increases with the increase in magnetic field strength. The experimental results have also been corroboratedmore » by a numerical simulation using a FitzHugh-Nagumo like macroscopic model derived from the basic plasma equations and phenomenology, where the noise has been included to represent the internal plasma noise. This macroscopic model shows MMO in the vicinity of the canard point when an external noise is added.« less
