Extent of Indoor Flammable Plumes Resulting from CNG Bus Fuel System Leaks 922486
A validated three-dimensional mathematical model was used to examine the extent of flammable plumes resulting from both large and small CNG leak scenarios inside a typical transit maintenance and storage facility ventilated at a rate of five air changes per hour. The leak rates used were based on an engineering and experimental analysis of actual CNG bus fuel system components.
The results showed that both large and small CNG leaks produced flammable plumes, such plumes extended from a half a bus length to several bus lengths away from the leak source, and the plume from a large leak formed a layer along the ceiling before being dispersed by building ventilation.
