Configuration effects of liquid fuel flameless combustion characteristics in a forward flow laboratory-scale furnace

This paper presents the experimental results of a cylindrical combustor under flameless combustion with liquid fuel (LF) for three different configurations. The three flow field configurations constituted varying combinations of tangential air inlet ports and a central atomizing fuel injection nozzl...
