Hydrogen Release and Combustion Measurements in a Full Scale Garage



Matthew Blais, Alexandra Joyce


Under the auspices of contract SB134109SE0612, The NIST contracted with Southwest Research Institute (SwRI) to perform a testing program designed to support NIST efforts on characterizing the behavior of hydrogen when released into enclosed spaces (e.g. leakage of hydrogen from a fuel-cell powered automobile parked inside a residential garage). The experiments were designed to characterize both the dispersion of hydrogen and combustion behavior of any flammable mixtures that were formed. The combustion behavior was characterized by visual observation, temperature, flame ion front speed measurements, radiative energy measurements, and the overpressures generated within the enclosure.
