Spontaneous Ignition of Fuel Droplets in Lean Fuel-Air Mixtures

Experiments have been carried out on the spontaneous ignition of single fuel droplets in lean fuel-air mixtures. The residence time, which is defined as the elapsed time from the introduction of the mixture into the furnace to the insertion of the droplet, is 15 s. The change in the chemical species concentration in fuel-air mixtures before the insertion of the droplet is predicted by the calculation of chemical reaction. In the case of lower...
