Laminar, mixed-convection, boundary-layer, nongray-radiative, diffusion flames
The two-dimensional, laminar, mixed-mode convection, boundary-layer radiative diffusion flame has been analytically investigated with emphasis on the nongray nature of the combustion products. The solution procedures include Shvab-Zeldovich approximation and von Mises transformation for the physical transport equations and the finite difference method for the computation of the transformed equations. The local radiative fluxes for nongray, gray and radiatively-ideal gases are prescribed. Twelve parameters that govern the flame characteristics have been identified. In addition to extensive results of distributions in the field variables and fluxes, the ratio of the radiation loss to the combustion energy evolved was computed and a radiatively-ideal gas having behaviors similar to the nongray gases was identified.
