| Abstract: | The experimental system on premixed flame fine structure is built up on the basis of visual combustion tube,which is used to explore the snapshot process and the acceleration characteristics of premixed flame propagation by the use of theoretical analysis and experiments.Flame acceleration laws of premixed gas with different concentrations of methane can be analyzed,as well as the transition laws from laminar flame to turbulence. |
