✦ Synopsis

Characteristics of ignition and subsequent flame spread of solid fuels (PBAA, PIB and paraffin waxes) in a hot oxidizing gas stream were studied experimentally by using a shock tunnel with a flat-piate fuel specimen placed parallel to the flow. Effects of freestream oxygen O content (20% -100%), freestream temperature (1270 -2100 K), freestream velocity (77 -275 m/sec) and diluent inert gases (N2, Ar) on ignition and flame spread behavior were studied. It was observed that, if the external heating rate is high or if the sample tends to pyrolyze at low temperatures, the heat feedback from the exothermic gas phase reaction is not important and the effects of freestream oxygen content are small for both ignition and flame spread. However, if the external heating rate is small or the sample tends to pyrolyze only at high temperatures, the heat feedback from the exothermic gas phase reaction is important and effects of freestream oxygen content are significant for ignition and flame spread.
