Low-temperature zone in a hydrocarbon-flame front VII. Structure of the flame front in hexane with aerosol fuel injection

Abstract

The flame front structure when hexane vapor is introduced into an O/sub 2/+ Ar gas mixture, and when hexane is introduced as an aerosol into the same gas mixture, is studied. The schemes of the equipment used to produce the mixtures specify thermostatic device, overflow device, burner, and sprayer. The flow system is explained. The flame temperature is measured with platinum thermocouples. Concentration profiles for the flames are derived. Differences in the temperature profiles in the initial part of the flames is explained. Differences in initial temperature do not influence the width of the low-temperature reaction zone.
