โœฆ Synopsis

Flame propagation through an array of vortices was studied with a model which incorporated the variation of the local burning velocity with stretch. Assuming incompressible flow, the mean burning velocities were calculated and compared to those of the Huygens limit. It was found that stretch causes a decrease in the mean burning velocity, and a mechanism which explains this trend was identified. The study also demonstrated that, as expected, stretch only has a significant effect on the mean burning velocity for vortices whose size is of the same order as that of the flame thickness.

A fully nonlinear evolution equation governing the propagation of a premixed flame through a large-scale spatially periodic shear flow is derived, and steady-state solutions are obtained numerically. The gas density is assumed to be constant across the flame, but the local normal burning speed is al
