Spectroscopic Techniques for Measurement of Velocity and Temperature in the DLR High Enthalpy Shock Tunnel HEG
Abstract
The theory of absorption techniques, including line broadening and shifts, along with a brief description of the spectroscopy of the seed species Rb, will be given. A brief overview of the diode laser itself and the experimental setup for the technique follow. Results are split into two parts: preparatory and calibration work in a test cell and a small test shock tube, followed by results in HEG, are presented. Here time profiles for gas temperature T(trans) and velocity u are given for various HEG run conditions.
