Formatted abstract
The Centre for Hypersonics at UQ uses the T4 Shock Tunnel to perform ground testing of prototype scramjet engines, however due to the relatively short duration of stable flows in the test section, uncertainty in the results is relatively high. This thesis uses L1d3 to perform a multivariate optimisation over six shock tunnel parameters with the aim of extending the duration for which stable stagnation pressures can be maintained in the nozzle supply region; thus extending the usable test duration and reliability of data gathered. Numerical simulations observed trends in the results and successfully identified several configurations that could substantially increase the nominal duration of stable stagnation pressures with little or no physical changes to the tunnel itself.
