Abstract
We consider electrogasdynamic (EGD) flow in the one-dimensional approximation. The conditions for transition through the speed of sound in EGD are formulated. The distribution of the basic parameters along the flow axis is presented. The concept of the efficiency of the EGD process is introduced, and its analytic expression is given.
A comparison is made of experimental and theoretical data on the parameter distribution and efficiency in EGD processes.
