Description
Summary:An experimental study has been carried out on several laminar premixed propene-air flames. The flame was stabilized in a dual flame burner and a two-dimensional distribution of its soot volume fraction was measured using the laser induced incandescence (LII) technique for three values of the pressure: 1, 3 and 5 bar at various equivalence ratios. For the atmospheric flames, the investigation has been extended to evaluate a primary particle diameter from the measured temporal decay time of the LII signal. For this, the local temperature of gas has been measured by shifted vibrational coherent anti-Stokes Raman scattering, which yields well-resolved, accurate temperature measurements in sooting and non-sooting flames. The obtained results were discussed and should present a set of benchmark data for improvement and validation of numerical codes predicting the soot formation in a one-dimensional flame.
