Laser Doppler velocimetry measurements in a laminar counterflow premixeddouble flame: comparison with numerical calculations,

摘要

Abstract: pe of this study is to obtain realistic comparisons between numerical calculations and laser Doppler velocimetry measurements of the axial velocity profiles for a large number of strained laminar premixed propane-air double flames. Stationary conservation equations for strained flames have been derived including one-parameter (strain rate) and two-parameter (radial pressure gradient and flow divergence) formulations. The experimental study consists in measuring the axial velocity across the flame by means of LDV system for stoichiometric, lean, rich and near extinction limit flames.!30
