Boron Particle Ignition and Combustion in a Shock Tube Using Time -Resolved Spectroscopy
Boron particles ignited in Ar/F/O2 mixtures show a rapid decrease by a factor of four in ignition and burning times as the mole fraction ratio XF/XO2 is increased from 0 to 0.25. For values of XF/XO2 greater than 0.5 there is little change of ignition burning time with XF/XO2 . Spectroscopic data …

On the formation of Friedlander waves in a compressed gas driven shock tube
Compressed gas driven shock tubes have become popular as a laboratory-scale replacement for field blast tests. The well-known initial structure of the Riemann problem eventually evolves into a shock structure resembling a Friedlander wave. In this thesis, we develop an analytical model to predict …

Effect of endplate on the blast wave profile in a compressed gas shock tube
… mechanisms of primary blast injury. When a pure shock-blast wave encounters a subject, in the absence of shrapnel, casing or gaseous products, the loading is termed as primary blast loading, and its effects can be studied using shock tubes. The wave profile of the shock-blast wave produced by the …
