Experiments are described in which hydrogen was released at the center of the floor of a real-scale enclosure having dimensions of a typical two-car residential garage. Real-time hydrogen concentrations were monitored at a number of locations. The hydrogen/air mixtures were ignited at pre-determined local volume fractions ranging from 8% to 29%. The combustion behavior and structural effects were monitored using combinations of high-speed pressure transducers and ionization gauges, standard thermocouples, hydrogen sensors, and digital, infrared, and high-speed video cameras. Experiments were performed both for empty garages and garages with conventional automobiles parked above the hydrogen release location.
► Hydrogen dispersion was measured in a two-car garage with and without a vehicle. ► Hydrogen/air mixtures were ignited for volume percents between 6% and 29%. ► The combustion behavior was characterized using various flame properties. ► Garage and vehicle damage due to hydrogen burning were qualitatively characterized.
