Abstract

It is shown that the adiabatic high Lewis number premixed gas flame spreading through a large-scale zero-mean time-independent periodic shear flow constitutes a bistable system with a hysteretic transition between stable propagation modes. A mildly non-adiabatic flame may be quenched provided the flow-field intensity exceeds a certain critical value. The study is motivated by the experimentally known phenomenon of flame extinction by turbulence.
