Ignition and extinction of liquid fuel drops-Numerical computations

Abstract

The equations for the steady state combustion of liquid fuel drops in an oxidizing atmosphere were integrated numerically for various fuel-oxygen systems. The results give a continuous description of the drop behaviour from the low mass burning rate kinetic controlled region to the high mass burning rate diffusion controlled region. Ignition was defined as the transition from kinetic to diffusion control and extinction as the reverse transition process. Ignition and extinction conditions were obtained as a function of ambient oxygen concentration for various reaction rates, reaction orders and stoichiometric ratios. © 1969.
