The results of a computational study of turbulent supersonic flows in a channel with a backward-facing step are presented, taking into account crossflow injection of argon and hydrogen jets. The calculations are performed at Mach number M = 4 at the channel entrance under the real flight conditions, which were realized in experiments in a hot-shot aerodynamic facility. The comparison of the flowfields is carried out for jet-to-freestream momentum ratio range J = 1 ÷ 6. It is shown that the degree of mixing, estimated from the uniformity index, increases with J increasing and with an increase in the molecular weight of the injected gas at the same J.

Coronal Structures

AbstractWe were successful in observing the solar corona during five solar eclipses (1973-1991). For the eclipse days the coronal magnetic field was calculated by extrapolation from the photosphere. Comparison of the observed and calculated coronal structures is carried out and some peculiarities of this comparison, related to the different phases of the solar cycle, are presented.
