Study of Leakage of Natural Gas and Distribution of Explosive Mixture in Building

Popis výsledku v původním jazyce

The paper deals with leakage of natural gas from domestic low-pressure piping. Spreading of the leaked natural gas in the building is dealt with and the areas are defined where local hazardous concentrations are formed. Mathematical CFD models provide broad overview of spreading of natural gas in dependence on the elapsed time from the start of leakage and on coordinates of the complex space. Since the flow is specified in the transition area between laminar and turbulent mode, both turbulent (for low Reynolds number too) and laminar models are tested. The accuracy of the models is verified by comparison with experiments. The paper should improve the understanding of spreading and distribution of mixture of gaseous fuels in confined spaces, and thus should lead to significant reduction of the risk of occurrence of fire or explosion, or to prevention of these hazards.
