Vented Explosion 1

Experiment ID Vented explosion 1
Short Description Experiments on 29.6% H2-air explosions in a 1 m3 vessel, closed and vented through 0.3 and 0.2 m2 openings.
What phenomena were studied Pressure reduction by venting
What phenomena / effects can be studied H2-air vented explosion, deflagration-outflow interaction during venting
Instrumentation Piezoelectric pressure transducers.
Test variables Vent area: 0.0, 0.2 and 0.3 m2.
Data description / Data completeness Smoothed experimental pressure dynamics data for: closed vessel explosion, vent areas 0.2 and 0.3 m2.
Data availability Publicly available.

Why were chosen Experiment on a vented H2-air deflagration, relevant to H2-air explosion mitigation by venting. Benchmark exercise to evaluate a model for explosion mitigation by venting.
Relevance to the project purposes Vented experiment relevant to hydrogen explosion mitigation (WP11 “Safety Measures”).
