Radiation-Affected Laminar Flame Propagation

where ~ = (Kp/rR ) '~ is the weighted nongreyness, K p and r R are the Planck mean and the Rosseland mean of the absorption coefficient, r = rM6 K is optical thickness, r M = (rprR)'/~ the mean absorption, 8 K the conduction flame thickness, P = 4o TM3/(~5 K) the Planck number, T M the adiabatic flame temperature, ~ the thermal conductivity, and w the albedo, the ratio of scattering to extinction.

Single Channel Laminar Flat Flame Simulations

In chapter 5, full 2-D reacting flow simulation of the flat flame burner was reported. A second order fit was found to be appropriate to describe the flame dynamics predicted by the CFD model. However, the phase relationship between the unsteady heat release rate (q′) and the incoming fluid stream velocity fluctuation (u′) was not correctly predicted. Also, the low frequency resonance phenomeno...
