Abstract :
Presents the results of a computation of gas-dynamic flows accompanying different stages of the electric breakdown in dielectric liquids. The expansion of a rectilinear channel in the plane and cylindrical cases was considered under conditions leading to self-similar flow. The inner structure of the liquid-“plasma” transition layer was investigated. The computations were carried out of flows with shock waves that are generated during the propagation of the tip of a single streamer and during the growth of a branched streamer structure. Different regimes of the streamer growth in viscous dielectric liquids were considered
