Short Description
| Test 2nd of 3 (HYC01, HYC12, HYC14). Combustion experiments have been carried out in large scale multi-compartment geometry consisted of curved channel (2.3x2.5 m cross-section and 15.5 m length) and canyon (6.3x2.5x16.4 m). Four repeatable obstacles with blockage ratio BR=0.3 installed in the channel. Canyon has been divided in four separate rooms connected with orifices. Uniform hydrogen/air mixture with concentration of 11.5% H2 was tested. Ignition in the channel (I1).

|
Why were chosen
| Very well instrumented, complete description, by the moment no similar results elsewhere are available
|
Relevance to the project purposes
| Series of three experiments can be used as integral experiments for the code validation on combustion process development in complex geometries on scales relevant to industrial.
