Measurement of scalar-velocity correlations in a turbulent diffusion flame
Simultaneous measurements of scattered light intensity and axial velocity have been made in a turbulent hydrogen diffusion flame in a co-flowing stream with accelerating and decelerating pressure gradients. The light-scatter signal obtained from the seeded nozzle fluid is used as a measure of hydrogen element concentration, and is processed to derive records of density and mixture fraction which are correlated in digitized form with the simultaneously recorded streamwise velocity component. Results reported include the mean and r.m.s. fluctuation of the streamwise velocity component and the density and correlations of the streamwise velocity component with the mixture fraction and the density as well as other correlations and Favre or density weighted averages. 27 refs.
