Displacement effect of a flame in a stagnation-point flow

Abstract

The interaction of a premixed flame with the flow near the front stagnation point of a body has rightly received considerable attention in combustion theory. Virtually all the investigations so far have been concerned with high strain rates, when the flame lies inside the boundary layer and can be extinguished. By contrast, we consider moderate strain rates, when the flame stands clear of the boundary layer and pushes the incident flow away from the body. The object is to determine this displacement effect, which is much more pronounced than that of the boundary layer.
