Abstract

The dynamic motion of a premixed Bunsen flame with burner rotation was investigated in normal gravity and microgravity. Rotating CH 4 air flames with mean flow velocities of U=0.6 and 1.1 m/s were studied for swirl number of 0-1.6. The motion of rotating flames under microgravity environment was recorded with the charge coupled device video camera of 30 frames and high speed video camera of 500 frames. The results indicate that the +1h periodic oscillating flame at U=0.6 m/s, is induced by the buoyancy instability, whereas the nonperiodic oscillating flame at U=1.1 m/s is due to the combined effect generated by the jet inertial force and centrifugal force.
