摘要:
Flame propagation through a periodic system or time independent eddies is studied. It is shown that at sufficiently low amplitudes of the velocity spatial variation, the effective speed of a passive flame has a global dependence on the underlying flow. However, at high amplitudes, the effective flame speed is determined by the local features of the flow. Simultaneously, the shape of the flame undergoes a transition from a smooth configuration to a cusped one.
