Experiment ID
| Safety tests on worst case scenarios
|
Short Description
|
Gas explosions, e.g. hydrogen-air, under defined conditions (gas concentration, ignition…) on industrial and commercial facilities and devices (e.g. fuel cell vehicles, lasers, hydrogen storage systems…)
The example shows a hydrogen air explosion inside a commercial 1000 liter plastics container

What phenomena were studied
|
|
What phenomena / effects can be studied
| Representation and reconstruction of hazardous scenarios in order to carry out damage effects to minimize potential risks and to verify constructive mitigation techniques.
|
Instrumentation
|
- Transient multi channel pressure measurement based on piezoelectric and resistive pressure transducers / amplifiers with high time resolution
- Multi channel Temperature measurements based on thermocouples
- High-speed spectroscopy (near infrared and ultraviolet and visible range)
- Background oriented schlieren technique (BOS)– visualization of expanding hot gas clouds and pressure waves with high time resolution
- Visualisation and documentation with high speed digital imaging systems
|
Test variables
| Highly time resolved pressure and temperature histories as well as the optical visualization techniques are suited to evaluate risks and to develop and optimize constructive mitigation techniques
