| HSL hydrogen detonation trials
|
| Short Description
| Stoichiometric volumes of hydrogen/air mixtures were forced to detonation by an explosive charge. Volumes of 5, 10 and 20 m3 were detonated.
The hydrogen/air mixtures were enclosed in a plastic-covered, wooden-framed structure, which also contained a limited array of instrumentation and a fan for mixing the gases.
The explosive charge was supported from the roof of the structure, so as to be suspended in the centre of the cubic frame.
|
| What phenomena were studied
| The over-pressures generated within the frame were measured.
The sound levels generated at a range of positions were recorded.
|
| What phenomena / effects can be studied
| Sound levels/over-pressures at a range of distances can be determined.
|
| Instrumentation
| Oxygen depletion cells were used to determine the gas concentration within the frame.
Kistler pressure transducers were used to measure pressures within and close to the structure at the point of detonation.
Measure and hold sound level meters were used to record the maximum sound level at a number of locations up to 500 m from the test site (The sound level can be used to determine the local over-pressure.
