Interplay between water-mist spatial continuity and droplet response in hydrogen deflagration suppression

An Eulerian–Lagrangian gas–liquid model was developed to investigate ultrafine water-mist suppression of hydrogen deflagration in confined spaces. Continuous, two-section, and three-section mist distributions were examined for droplet diameters of 10–45 μm. Continuous mist mainta...

Effects of ambient temperature on flame propagation characteristics of methanol spray-hydrogen explosions

Methanol-hydrogen fuel forms explosive spray droplet clouds during storage and transport. Therefore, understanding the propagation characteristics of spray flames is crucial for safe application. This study systematically investigates the impact of ambient temperature, methanol c...
