Numerical Study of the Interaction of Shock-Heated Plasma Flows with Transverse Magnetic Fields

抄録

The magnetohydrodynamic (MHD) equations for the interaction of shock-induced plasma flows with transverse magnetic fields are solved numerically by taking into account the radiative energy loss; real gas effects such as variable degrees of ionization are also considered. The one-dimensional flow is assumed. The results are compared with experimental data obtained with an arc-driven shock tube whose test section is similar to the MHD generator of the Faraday type. The continuum radiation intensity is measured as a function of time. Good agreement is obtained in the time histories of the calculated and measured continuum radiation intensities at the position where the flow is one-dimensional.
