Experimental Activities on the MHD Interaction in a Hypersonic Air Flow Around a Blunt Body

This paper deals with the design of an experiment devoted to MHD flow control, to be performed in CIRA GHIBLI hypersonic facility. The criteria utilized to define the proper test conditions and to design and realize the model are here described. The expansion in the nozzle has been investigated through numerical simulations in order to have a preliminary estimate of the ionization degree and of the heat fluxes over the test article. Moreover, an MFD code has been used in order to calculate the expected interaction effect, under the assumption of low Rem. The same procedure has been utilized for the design of an MHD test to be performed in the CIRA SCIROCCO facility.
