CHARACTERIZATION OF THE DENSITY FIELD BY RAYLEIGH SCATTERING IN PREMIXED TURBULENT CONICAL CH-4 - AIR FLAMES
Rayleigh scattering is applied to determine the spatial and temporal characteristics of six turbulent premixed conical methane/air flames stabilized by pilot flame on the rim of a 16mm inner diameter brass tube of 600mm long. The cold flow turbulence structures are determined by laser Doppler Anemometry. The main global parameters of the investigated flames are as follows: Axial and several transversal evolutions of p, p', P(p), E-p(n) are determined for each flame. The turbulent brush thickness, integral and dissipation time scales of the fluctuating density field and the reactants and products mean passage times are deduced and discussed in the light of recent models dealing with the statistics of flame passage frequencies.
