ABSTRACT
This chapter discusses a peculiar comparison between an external control of the process and the plasma temperature measurements. The associated measurements were Coherent Anti-Stokes Raman Scattering (CARS) for the temperature determination and Laser Doppler Anemometry for the velocity in the case of the model validation. The CARS system was a commercially available bench upgraded for narrowband/broadband configurations. Though the modeling of heating a cold wind by a plasma jet belonged to the general frame of the 3D turbulent compressible fluid mechanics, the model predictions were essentially validated in terms of the industrial interest. The sophisticated laser metrology have brought a wide variety of information on the plasma generator behaviour.
