Abstract
The stationary flow of an Ionized gas in a mum: coaxial channel with a constant or slowly varying cross section is investigated. The electric and magnetic fields are assumed given. Viscous friction and heat are neglected. A system of nonlinear differential equations for the dimensionless variables characterizing the flow is obtained and investigated for the case of constant fields. The regimes of motion are studied in relation to various parameters. It is shown that the rotational velocity of the gas is an important and, under certain conditions, a unique parameter determining the energy balance of the flow, i. e., the increase in the sum of the kinetic energy of translational and notational motion and the thermal energy of the gas.
