The blast mitigation mechanism of a single water droplet layer and improvement of the blast mitigation effect using multilayers in a confined geometry

Localized water mist method enabling superior premixed hydrogen-methane-air deflagration mitigation in semi-confined space

“…Although the deflagration mitigation effect of small-diameter WM is substantial, literature data [35] indicates a significant reduction in the deflagration mitigation effectiveness of small-diameter WM under obstacle conditions. Despite the significant mitigation effect of 6-50 μm WM under spraying throughout the entire deflagration space conditions, researchers were unexpected to find a promoting effect when using 45 μm WM in localized region, while larger droplets of 160 μm demonstrated excellent mitigation effect [42]. However, quantitative studies based on CFD indicated that this phenomenon is related to the breaking effect of the deflagration shockwave on droplets [43].…”
