FZK-R 049809

Experiment ID FZK-R0498_09
Short Description Test 3 of 3 (MC003, MC012, R0489_09). Combustion experiments have been carried out in obstructed tube of 350 mm i.d. and 12 m long. Repeatable obstacles with blockage ratio BR=0.3 at distances equal to i.d. Hydrogen/air mixture with concentration of 15% H2 was tested.
What phenomena were studied Flame acceleration up to detonation transition
What phenomena / effects can be studied Deflagration-to-detonation transition, steady-state detonation propagation in obstructed channel
Instrumentation Measurements include 24 piezoelectric transducers, 24 collimated photodiodes.
Test variables Hydrogen concentration, tube diameter
Data description / Data completeness All pressure and photo-diode recordings in digital form
Data availability Publicly accessible
Source of data / Reference FZK Technical Report
Why were chosen Very well instrumented, complete description
Relevance to the project purposes Series of three experiments can address effect of mixture composition on flame propagation in obstructed geometry. Has primary importance for code validation.
