Modelling of a bluff-body nonpremixed flame using a coupled radiation/flamelet combustion model
journal contribution
posted on 2009-11-23, 09:43 authored by Mamdud Hossain, J.C. Jones, Weeratunge MalalasekeraWeeratunge MalalasekeraA coupled radiation/flamelet combustion modelling technique is applied to the simulation
of a bluff-body flame. Radiation heat transfer is incorporated into the laminar flamelet model
for turbulent combustion through the enthalpy defect. A new method is developed for generating
flamelet library with enthalpy defect. The radiation within the flame is modelled using a ray tracing
approach based on the discrete transfer method. The predicted results are compared with the reported
experimental data. Comparison shows that the effects of radiative heat transfer on the temperature
and major species are small for the flame considered. However, a significant improvement in the
prediction of OH is achieved when radiation heat transfer is included.
