Abstract

The interaction of a premixed flame with the flow near the front stagnation point of a body has been reconsidered in this paper for the case of moderate strain rates when the flame stands clear of the body. We provide a detailed solution which includes the determination of the flow field as affected by the burning, the flame standoff distance, and the displacement of the incident flow. In particular, we determine the standoff distance at which extinction takes place when the Lewis number associated with the deficient component of the mixture is sufficiently large. Unlike most previous studies this extinction curve is based on an analysis which fully accounts for thermal expansion.
