Validation of the Kinetic Soot Model: An Experimental and Theoretical Study on Soot Formation using LII and SV-CARS

ABSTRACT: Temperature and soot concentration measurements from laminar, premixed flames at different conditions (pressures P, equivalence ratios φ and fuels), provide an excellent data base for the modelling of soot formation. For the verification of numerical simulations of sooting flames, the use of accurate, spatially and temporally resolved data measured with non-intrusive in situ meas-urement tools is necessary. We present the application of a recently developed technique for tem-perature measurements in sooting flames. Soot concentrations measured by laser-induced incandes-cence (LII) are compared to calculated profiles of soot formation, based on the measured temperatures. The overall agreement is quite satisfactory for the experimental conditions presented.
