Numerical Simulation of the Shock Wave Propagation in the Discharge Chamber with Megaampere Discharge in High Density Gas
摘要
Abstract
Numerical simulation of the shock wave propagation in the discharge chamber with the high-current discharge in high density hydrogen at initial pressure of 0.1–32 MPa under non-stationary energy release at current rise of rate of 10 GA/s was carried out by the finite-differences method. The source of the disturbance (shock wave) was a forming discharge channel in the interelectrode gap along the axis of the cylindrical chamber. The power disturbance of the source was given by the experimental power value in near-axis area.
