Abstract
In order to clarify the effects of vortex core radius on the vortex bursting phenomenon, the premixed flame propagation in swirling flow has been examined by the numerical calculation for various vortex core radii. In this calculation, the flame is fixed in the computational domain by adding an axial flow to the unburnt premixed gas so as to obtain the steady state propagation characteristics. The obtained results are as follows : The obtained relationships between the maximum circumferential velocity and the flame propagation speed or the flame region radius agree with the previous studies. Moreover, the effect of vortex core radius on the flame propagation speed and flame shape are clarified. When the vortex core radius is less than 7 mm, the flame propagation speed is dependent on both the angular speed and the vortex core radius. On the other hand, when the vortex core radius is more than 7 mm, the flame propagation speed is directly proportionate to the angular speed not but the maximum circumferential speed, and it is not dependent on the vortex core radius.
