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.

在这项研究中，我们开发了通过高速PIV测量来同时显示柱状玻璃内稀薄预混火焰和流场的技术。为了研究预混火焰在旋流燃烧器中的非定常火焰行为，研究了旋流预混燃烧器中火焰的传播特性。为了研究火焰传播特性，采用了两种不同的混合供气技术。在旋流闭合中心旋流器的预混器中，火焰尖端被高度拉伸，火焰被熄灭，阻止了火焰的进一步向上传播。在开式中心旋流器的预混器中，证实了旋流器中心孔撞击流产生的轴向高速流区将火焰压回到预混合器下游。
