Formatted abstract
The purpose of this research was to analyse and explain anomalous data in a particular high pressure run of the shock tunnel “T4” at The University of Queensland. The tests used a 6mm steel plate diaphragm, 12.5 MPa reservoir fill pressure, 156 kPa driver fill pressure, 150 kPa test gas fill pressure, and an argon-to-helium ratio of 7/13.

CFD analysis with L1d3 was performed for the test conditions and found: that there was an excessively high pressure peak in the compression tube for some time after the primary diaphragm ruptured; shock waves formed in the compression tube propagating into the shock tube and catching up to the primary shock; an under-tailored interface condition caused expansion waves to reflect into the test flow; and an expansion wave, created when the primary diaphragm ruptured, penetrating the interface into region 5 and causing a pressure spike in the test region.

This was all due to the initial conditions not being able to satisfy the tuned-tailored conditions.
