Abstract
This thesis presents an overview of modifications made to an existing shock tube facility that will facilitate future studies involving hydrogen and nano-particle combustion. The modifications were made to the shock tube located in the University of Calgary’s High Speed Aerodynamics and Energy Research Laboratory. Specific changes were made to the driver section utilizing shock tube tailoring with the aim of increasing available test times from 3 ms to 10 ms at 900 K end wall temperatures. A novel method of determining the local gas mixture based on measured shock velocity and shock tube pressure data was also developed and tested with mixtures of nitrogen and helium. Results of these tests show that that the method used in this study can estimate the mole fraction of helium within 4% of the expected value.
