Scientific paper

A new test case complementary of the three defined test cases for the workshop is presented in this paper. It deals with the simulation of the radiative emission of a nonequilibrium expanding plasma flow. Spectroscopic measurements were performed at the exit of the plasma generator of the SR5 plasma wind-tunnel available at the Laboratoire d'Aérothermique. These include high resolution line of sight spectroscopic measurements as well as local lower resolution spectroscopic measurements using the Abel inversion technique. A local measure of the radiative properties of the jet is therefore available. It is proposed to model the internal expanding plasma flow to different levels of complexity and to use the obtained results in order to reproduce the measured radiative spectrum. Calculations may include one or two-fluids descriptions (heavy particles and electrons), taking into account the molecules vibration temperatures, as well as the electrons temperatures, or even including state-to-state models. A calculated flowfield could be provided to the groups solely interested in the simulation of the plasma flow radiation at the nozzle exit.
