Formatted abstract
The University of Queensland prides itself at being on the forefront of hypersonics research. The T4 shock tunnel facility has been of great service in the development of the scramjet project. In order to remain at the top of the field, it is necessary to investigate improvements that can be implemented. As such this thesis was undertaken to perform an initial feasibility study into the implementation of a combustion driver for the T4 facility, replacing the current piston. This should serve to increase test times, along further complexity of experiments to be run within the facility.

Throughout this investigation, ways of improving the L1d3 simulations of T4 were identified. In particular, an investigation into the time it takes for the steel diaphragm of the facility to rupture was undertaken. The results of this found that it should be considered in future simulations.

In terms of implementing the combustion driver into T4, further investigation is indeed warranted as initial, basic simulations returned positive results, with estimates of increasing test times to 8 milliseconds.
