Explosion Parameters of Gaseous JP-10/Air Mixtures

This paper describes flammability measurements and data on the missile fuel, JP-10. The measurements include maximum explosion pressure, maximum rate of pressure rise and limiting flammability concentrations. Through a series experiments, the influences of the concentration of gaseous JP-10 in air on the explosion pressure and on the rate of explosion pressure rise have been analyzed, and the results are discussed. The explosion pressure of gaseous JP-10/air mixtures reached their highest values within the studied range at a concentration of 1.88%. The variation trends in the explosion pressure and the rate of pressure rise of gaseous JP-10/air mixtures with volume % appear similar. When the volume % of gaseous JP-10 lies in the range 0.5-1.8%, the explosion pressure and the rate of pressure rise for gaseous JP-10/air mixtures increase with the volume %, while in the range 1.8-5% these parameters decrease with the volume %. The flammability limits of gaseous JP-10/air mixtures are near those of gaseous n-decane/air mixtures. However, the maximum explosion pressure and the maximum rate of pressure rise of gaseous JP-10/air mixtures are much higher than those of gaseous n-decane/air mixtures.
