In the frame of the PRESLHY project more than 100 combustion experiments with cryogenic
hydrogen-air-mixtures were made in a semi-confined obstructed channel. In the experiments a
large H2-concentration range from 10 vol% up to 60 vol% as well as different blockage ratios
(BR = 0, 30 and 60%) were investigated. Besides the main experiment series at cryogenic
temperatures (approx. 100 K inside the channel) most of the experiments were also performed at
ambient temperature for comparison.
