Optical Characterisation of the Thermo-Chemical-Geometric State of High Explosive Fireballs
Abstract
The overarching aim of this project was to develop advanced diagnostics to allow for quantification of the physical state of an explosive reball in the near- field region. The original objectives for the project were: 1. The continued development of a dataset of spatial and temporal loading distributions arising from the detonation of near-field free air charges for a range of explosive types. 2. Optical temperature measurement of the reball using a specially altered high-speed video (HSV) camera. 3. A high-speed, non-intrusive, spectroscopy-based optical measurement system for the gas species present in the reball. 4. 3D maps of the reball expansion for different explosive types and shapes using stereo Schlieren techniques. 5. Quantification of how the thermo-chemical state of the reball affects the loading in the near- field region.
