VARIABLE PROPERTY EFFECTS ON LIQUID DROPLET COMBUSTION

The combustion characteristics of a liquid fuel droplet burning in an oxidizing atmosphere are considered. Formulas for fuel burning rates, flame temperature, and position, as well as fuel and oxidizer concentration and temperature profiles, are given which include the effects of very general transport property variation. The relative importance of diffusion of species and heat conduction in the system is discussed. Specific calculations are shown for 1) power law temperature variation of thermal conductivity and binary diffusion coefficient, and 2) benzene droplets burning in air. © 1968 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
