Jet Fuel Vapor Ignition within a Duct Thermal Insulation 2004-01-2574

A test setup was built to identify the ignition of jet fuel vapor-air mixtures within an insulation media and induced by a hot duct surface. The external diameter of the duct was 76.2 mm (3 inches) and covered with a 12.7 mm (0.5 inch) layer of ceramic fiber insulation, which had its pores completely filled with fuel vapor and air mixtures. The ignition was detected by thermocouples installed in insulation media and confirmed by chromatography and mass spectrometry. In order to design the experimental apparatus and allow behavior investigation in other operational conditions, a mathematical model was developed.
