Oscillating flames in micro-combustion
Combustion and Flame, 2016 New experimental results that demonstrate the existence of oscillating flames in micro-combustion are reported here. The results showed the presence of oscillating regimes with different behaviors in the transition between the stable flames, FREI (Flame with Repetitive Extinction and Ignition), and weak flames.
