CFD Rebuilding of Cold Hypersonic Flow in GHIBLI facility

Carlo Purpura, Eduardo Trifoni, Federico D'Auria, Stefano Carletta, Francesco Paolo Barrera


The numerical analysis represents a powerful instrument to support experimentation, both in the preliminary stage and
in the post-processing. In this last case, it can be useful to conrm the experimental results and to rebuild the physical
phenomena as well. The subject of this paper is the numerical rebuilding process, by means of the FLUENT code,
of the thermo- uid dynamic conditions achieved in the GHIBLI Plasma Wind Tunnel during a cold ow experimental
campaign. Such a rebuilding process has produced results which agree well with the experimental ones, both measured
or calculated by means of the isentropic equations. The rebuilding conrms the achievement of the hypersonic conditions
in the Test Chamber of the facility, operating with air ow at low enthalpy.
