- Abstract
- The results of a series of flame acceleration tests performed at the Defence Research Establishment Suffield (DRES) are reported. These tests were performed in order to assess the potential for flame acceleration and transition to detonation in simulated industrial environments with repeated obstacles. The experimental apparatus consisted of a channel 1.8 m x 1.8 m in cross-section and 15.5 m long, connected to a 0.9 m diameter tube, 8 m long. The bottom of the channel was confined by the ground, and the sides were confined by plywood or plexiglass sheets. The only top and end confinement was due to the plastic envelope which was used to seal the configuration to contain the explosive gaseous mixture. Two obstacle configurations were tested, corresponding to 500 mm or 220 mm diameter tubes mounted across the channel at regular intervals.
