Evaluation of Probe-Material Thermal Interaction in Plasma Wind Tunnel Tests by Means of IR Thermography and Thermal Inverse Modelling
Boekbijdrage - Boekhoofdstuk Conferentiebijdrage
The VKI Plasmatron facility allows to reproduce the high-enthalpy chemically reacting boundary layer
over a re-entry body. Test conditions are suitable for qualification of thermal protection systems and
material response studies. The present work combines numerical and experimental procedures to rebuild
the thermal steady-state of the test probe subject to the plasma flow. The proposed analysis allows to
account for multidimensional heat transfer eects in determining the stagnation point heat flux over the
material sample. The technique is applied to metallic and silicon-carbide specimens, highlighting the main
parameters which aect their thermal response.
