One-dimensional electro-gasdynamic flow with shock waves and a small electrohydraulic interaction parameter: PMM vol. 36, n≗5, 1972, pp. 874–879

Abstract

The one-dimensional flow of a unipolarly charged gas between an emitter and a collector is considered for a given discontinuous variation of velocity in the working gap (e. g. in the presence of a gasdynamic shock wave and a small parameter of electrohydraulic interaction). The effects of position and intensity of the velocity discontinuity and of the difference of electrode potentials on the flow properties are determined. It is shown that solutions yielding zero surface charges at the discontinuity can only be obtained in a limited range of variation of determining parameters. Outside that range innumerable solutions yielding nonzero surface charges are possible. A classification of solutions is made on the basis of conditions proposed in [1].
