Abstract
The MHD interaction around a conical test body in a hypersonic argon flow is experimentally investigated. The aim of the experiment is to produce a data base to be used for the validation of numerical codes for the analysis and the simulation of the magneto-fluid dynamics in hypersonic flows. In these experiments the flow is realized in the high-enthalpy arc-heated hypersonic wind tunnel - HEAT - of Alta (Pisa-Italy). Speeds at Mach 6 have been realized. In the present experiment the flow and the plasma characteristics have been determined. The MHD interaction is obtained in the shock layer of a conical test body placed at the exit of the hypersonic nozzle. The electrical configuration realized, allows enhancing the effect of the MHD interaction on the plasma parameters. This is done by utilizing the Hall field to generate the MHD interaction and by short-circuiting the Faraday current inside the%I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
