| Short Description
| Deflagration of 29.5% (by vol.) hydrogen-air quiescent mixture in the 6.37 m3 closed spherical vessel (diameter 2.3 m). Central point ignition source. Initial temperature is 373 K, initial pressure 97 kPa.
|
| What phenomena were studied
| Pressure dynamics of hydrogen-air deflagration in closed large-scale vessel.
|
| What phenomena / effects can be studied
| Wrinkled flame front propagation and pressure build up.
|
| Instrumentation
| Pressure transducers
|
| Test variables
| Hydrogen concentrations (only stoichiometric mixture is offered for SBEP).

|
| Why were chosen
| Large-scale experiment on hydrogen-air deflagration in closed vessel (published in peer reviewed journal). One of the possible scenarios in practice is deflagration in closed space. Convenient basic benchmark case to evaluate a model performance for: flame front propagation, pressure dynamics and absolute pressure after explosion.
|
| Relevance to the project purposes
| Large scales of the experiment and initially quiescent mixture conditions are relevant to the problem of industrial hydrogen safety.
