- Abstract
- The interaction of a laminar diffusion flame with two- and three- dimensional vortex structures is considered, in which the flame becomes severely distorted and is strained in its own plane. The resulting curved flame sheets are treated by applying the boundary layer approximation locally until neighboring flame sheets come sufficiently close to interact and consume the intervening reactant, thus creating a core of combustion products with external isolated flame sheets. Straining of the flame due to interaction with the vortex causes an augmentation of the combustion process. Three such examples are considered here; one in which the flame is deformed by a viscous line vortex of circulation, one where a flame sheet interacts with a viscous vortex undergoing constant axial straining, and one in which heat release (and the subsequent change in density) occurs as the flame is distorted by the vortex structure.
