  • Effects of Vortex Stretching and Merging on Flame Propagation Speed in Vortex Bursting

抄録

<p>The vortex bursting is a high-speed flame propagation phenomenon along a vortex. In this numerical study, the effects of vortex stretching and vortex merging on flame propagation speed in the vortex bursting was investigated. As a result, firstly, it was found that the flame propagation due to the vortex driving mechanism of the vortex bursting was possible even along a small-scale vortex with a size close to the Kolmogorov scale. Secondly, it was shown that the flame propagation speeds increased both in cases of small-scale vortex formed by stretching and of large-scale vortex formed by merging. The magnitude relation of their flame propagation speeds in turbulent combustion field was discussed.</p>
