Abstract: The influence of water sprays on gas flame propagation was experimentally studied. The present results suggest that the mitigating effect of…… Key words: explosion; flame propagation; water sprays
1 Introduction
The effectiveness of water as a fire-fighting agent is universally recognized and water sprays are widely used in protecting structures and against fire. Recently, researchers have again focused on studying water sprays as a means of mitigating gaseous explosions[1~5]……
