The effect of component distribution in a capacitative energy storage unit on the nature of plasma flow in a coaxial channel

A theoretical investigation, on the basis of the two-dimensional MHD approximation, of the effect of the distribution of the RLC components of a capacitative energy storage unit on the nature of plasma flow in a coaxial channel is presented. An analysis of variations of the dimensionless parameters of the flow equations and variations of the number and distribution of the RLC networks has revealed the existence of the following flow regimes: (1) a nonstationary regime, when the plasma jet does not have time to leave the coaxial accelerator before the end of the discharge in the capacitance unit, and (2) a quasi-stationary regime, when plasma velocity attains a maximum at the exit from the accelerator channel.
