Abstract
AbstractIn extension of previous work a comparison has been made between experiments and numerical simulation results across the flame front of an atmospheric pressure methane/air counterflow diffusion stabilized in the forward stagnation region of a cylindrical porous burner plate. Temperature profiles have been measured by CARS spectroscopy on molecular nitrogen. The experimental data are compared with results of numerical calculations using a computer code based on a one‐dimensional boundary layer approximation. This work covers pure diffusion flames at different strain rates as well as partially premixed flames at two stoichiometries and strain rates. The results indicate good agreement between measured and calculated temperature profiles with regard to peak temperature location of the flame front, temperature gradients and overall shape of the non‐premixed and partially premixed flames, respectively.
