Abstract
Liquid hydrogen receiving terminal(LHRT)is exposed to great hydrogen-leakage threat due to the frequent operation and complex components.The evaluation of the consequences resulting from a potential liquid hydrogen leakage is therefore essential.Numerical simulation of liquid hydrogen leakage based on a pseudo-source model was conducted at the operational Kobe LHRT in Japan.The effects of leakage apertures and wind speed and direction on the consequences of accidents under the current station structure were assessed in terms of both dispersion and explosive overpressure hazards.The results show that larger leakage apertures,lower wind speeds and the presence of larger obstacles in the downwind direction all cause the hydrogen cloud to build up to a larger volume and produce a larger peak explosive overpressure.The maximum explosive overpressures are all above 0.13790 bar,which would cause moderate damage to the building and moderate injury to personnel.The overpressures in the control room are all below 0.06895 bar and within safe limits.关键词
