Vibrational Relaxation in the Products of Hydrocarbon Fuel Combustion,

Abstract

The oscillating relaxation time in the combustion products of a hydrocarbon fuel as it flows from a nozzle under supersonic flow conditions was calcualted. For certain components the duration of the oscillating relaxation is comparable to the characteristic gas dynamic duration of flow. This leads to the fact that the oscillating temperature of the gases at the output of the nozzle essentially exceeds the progressive temperature. (Author)
