Abstract

An axisymmetric curved-wall jet (CWJ) burner is designed with flat and concave tips and the characteristics of flame stabilization is investigated experimentally. To identify the flame stabilization mechanism in the CWJ burner, the planar laser induced fluorescence (PLIF) technique for OH measurement and the coherent anti-Stokes Raman scattering (CARS) technique for temperature measurement are applied. A broadband CARS technique was used for temperature proving. The present results demonstrating higher temperature near the burner tip compared to that of the boundary of recirculation suggest that the flame is stabilized through a recirculation zone. The results that the blowoff velocity is much higher for flat and concave tips than the spherical tip support this argument.
