The effects of external magnetic and electric fields on the position of attached shocks in a supersonic diffuser were studied. Experiments were conducted at a Mach number at the diffuser inlet of M = 4.3. The working gas was Xe plasma, formed using a reflected shock tube with an accelerating convergent-divergent nozzle. Magnetohydrodynamic experiments with an external transverse electric field in the decelerating and accelerating regimes and experiments with a longitudinal electric field were carried out. The interaction of the flow with the external fields in different parts of the diffuser was achieved by circulating current through different segmented electrodes. It has been found that application of external fields near the inlet leading edge is the most efficient.
