Structure of the current layer and modes of magneto-gasdynamic interaction with supersonic gas flow

Numerical simulation of the interaction of the current layer in the magneto-gasdynamic channel with the induction of external magnetic fields of $1$, $2$, and $4$ T and various load resistance values has been carried out. Features of the energy balance and differences in the temperature profiles in the current layers, which were both streamlined by a nonconducting gas flow and completely covered the channel cross section and interacted with the flow like a piston, are revealed. The dependences on the load resistance are obtained for the current, coefficients of current-layer permeability, and enthalpy conversion.
