Abstract

The laminar burning velocity and the turbulent burning velocity of propane-air homogeneous mixtures in a closed vessel were successfully measured from the difference between flame propagation speed, Wf, and unburned gas velocity, Ul, ahead of a flame front. Ul was measured with LDA, and Wf was determined by measuring the time of flame travel over a fixed distance. The flame front was detected by the deflection of a laser beam owing to the rapid change in the refractive index at the flame front. It was found that these measured values were reasonable as compared with the values determined from the configuration of flame and the combustion pressure.
