Estimation of Discharge Plasma Parameters in Flow past Blunted Body under Conditions of Unsteady MHD Interaction

摘要

The paper shows the results of an experimental study of a high-voltage pulsed discharge under non-stationary magnetohydrodynamic (MHD) interaction in a flow around a blunted body in a hypersonic air flow M = 6. Two methods are described for determining the hydromagnetic interaction parameter (Stuart number): according to the results of measurements of discharge characteristics and plasma visualization, and another way - in terms of the pressure drop at the critical point of the model.
