Evaluation of a Concentration Probe for Application in a Supersonic Flow Field

Abstract

Aspirating, concentration probes are used to measure binary gas concentrations in a supersonic flow. In the past, a tank discharge method has been used to calibrate concentration probes. An alternate calibration method has been developed and tested on a probe in a steady, subsonic/sonic flow. This study evaluated the calibration and performance of a concentration probe in a steady, supersonic flow over a range of mixture ratios of air and helium. The results of this study and a comparison of the two calibration methods are presented. Anemometers, Hot Wire Anemometers, Calibration, Probes, Supersonic Flow
