Experimental study of plasma flow in a disk MHD channel under conditions of spontaneous formation of a current layer


The results of an experimental study of the plasma flow in a disk channel under conditions of strong hydromagnetic interaction are presented. It is shown that if the condition RemH 0 2 /8π≥0.2 is satisfied for the magnetic Reynolds number at some point of the stream, then a current layer develops at that point characterized by a high electric-current density and high conductivity and temperature. The formation of the current layer leads to strong local retardation of the stream, the appearance of a shock wave, and a number of other nonlinear hydromagnetic phenomena. The experimental results are in agreement with theoretical studies conducted earlier.
