STRUCTURE OF THE FLOW-FIELD OF A NONPREMIXED GAS-JET FLAME IN CROSS-FLOW

Experimental studies on nonpremixed turbulent flames in cross flow are necessary as the current analytical and numerical tools are unstable to provide acceptable quantitative information about their complex flo w fields. This study, which complements the results of a previous stud y by the authors on the flame structure in the stabilization region of a partially lifted turbulent diffusion flame in cross-flow (TDFCF), p resents the measured turbulence quantities in the flow field of the sa me flame. Results include mean velocities in the cross-stream and span wise directions, the vertical and horizontal components of fluctuating components of velocity Reynolds stress, power spectra, and autocorrel ations useful for developing and validating theoretical models of TDFC F in the moderate momentum flux ratio range.
