Introduction

 

The burner consists of two steel tubes mounted in a vertical counter flow configuration. Thermostatted brass disks are attached at the exit plane of each tube, in order to establish reproducible boundary conditions comparable with those in recent DNS work [2,3]. Two-dimensional Laser Induced Fluorescence (LIF) Imaging of the OH radical and UV chemiluminescence were employed to characterize the flames. The OH LIF signal was excited by pumping the A-X (1-0) P1 (7) line. Broadband, temporally integrated signal detection in the A-X (0-0) and (1-1) band used a gated camera with a suitable interference filter. The same filter and camera, with longer gate times, were also used for detecting UV chemiluminescence.

The major species and temperature distribution are investigated using a 1-D Raman scattering setup (see Fig.below). Particle Image Velocimetry (PIV) was employed for 2-D flow field measurement.
