Experimental Investigation on the MHD Interaction around a Sharp Cone in an Ionized Argon Flow

In this paper the MHD interaction around a conical body in a in hypersonic argon flow is experimentally investigated. The hypersonic flow is obtained from the high-enthalpy archeated wind tunnel of Alta (Pisa) at Mach 6. The experimental activity are performed to produce a data base of measurement that can be conveniently be utilised for the validation of numerical codes developed for the analysis of the MHD interaction. Test are performed at various plenum chamber stagnation pressures. In order to characterise the plasma parameter in the free stream, microwave and emission spectroscopy has been utilised. The magnetic flux density is produced by an array of three magnets located in the test body
