Explosion Characteristics of Hydrogen Gas in Varying Ship Ventilation Tunnel Geometries: An Experimental Study

Hydrogen is widely regarded as a key element of prospective energy solutions for alleviating environmental emission problems. However, hydrogen classified high-risk gas because its wide explosive range, high overpressure, low ignition energy, and fast flame propagation speed compared with those hydrocarbon-based gases. In addition, deflagration can develop into detonation in ventilation or explosion guide tunnels if overpressure occurs, leading to the all combustible quantitative evidence an increase unavailable characteristics are insufficiently understood. Therefore, this study investigated chamber shape pipe ship compartment. The effect tunnel length on was examined experimentally. For verification, size analyzed experimental values gases (butane LPG (propane 98%)). database be used risk analyses ships when designing holes piping systems developing new safety guidelines carriers hydrogen-fueled ships.
