Research Abstract

In this study, we developed simultaneous visualizing techniques of lean premixed flame and flow fields in a cylinder glass by high-speed PIV measurement. We present characteristics of flame propagation in a premixed burner with swirling flow in order to investigate unsteady flame behavior in the premixer. Two kinds of mixture gas supply techniques were used in order to investigate the characteristics of flame propagation. In the premixer of the closed center swirler with swirling flow, the tip of the flame was highly stretched and received flame extinction and the flame propagation further upward was prevented. In the premixer of the open center swirler, it was confirmed that flame was pressed back to downstream of the premixer by the axial high velocity region generated by impingement flow from center hole of the swirler.
