It is shown that the nonadiabatic premixed flame propagating through zero-mean, time-independent, periodic shear flow is quenched provided the flow-field intensity exceeds a certain critical level. In the nearly quenched flame at the points of its highest stretch, where the flame temperature is lowest, the stretch intensity appears to be independent of the flow scale, provided the latter is large enough. It is argued that the results obtained may be relevant to the experimentally known phenomenon of flame quenching by turbulence.
