Abstract:

The combustion of a liquid fuel drop is considered in the neighborhood of the classical large Damkohler Number or Burke-Schumann limit, when the activation energy theta is also very large. By permitting M, the fuel vaporization rate, to differ from its equilibrium value by 01theta, the entire strong-burning branch is described. Analytic criteria are deduced for the solution to be valid, and these permit explicit predictions of when M is a multiple-valued function of the Damkohler Number.
