- Abstract
- Measurements and predictions of temperatures and radiation for large two-phase non-premixed flames burning heptane or crude oil and methane in air are reported. Analysis involves the locally-homogeneous approximation (LHF), a k-e-g turbulence model and the conserved scalar formulation. State relationships for the mixtures are estimated from those of the individual fuels. Radiative heat fluxes are obtained using the discrete transfer method and the narrow band analysis. Methane/air flames are studied as a baseline. The analysis underpredicts the temperature by ten percent and the heat fluxes by thirty percent for the two phase flames.
