Manifold assumptions in modeling radiation heat losses in turbulent nonpremixed combustion

Accurate predictions of heat losses in turbulent combustion are critical for accurate predictions of pollutant emissions such as nitrogen oxides and soot due to their extreme sensitivity to the underlying gas-phase temperature and composition. Reduced-order manifold approaches to modeling turbulent combustion require an additional enthalpy or enthalpy-like parameter to account for these heat losses. The particular focus of this work is radiation...
