Abstract
This work studies the Turbulent Radiation Interactions (TRI) in a heated turbulent plane jet of water vapor discharging into a parallel low speed co-flow of cold water vapor. To this purpose, a comparison between the averaged radiative power from a coupled direct numerical simulation and the radiative power field when computed from the averaged temperature field is presented. This comparison allows a quantification of the TRI when turbulence is modelled by the Reynolds Average Navier-Stokes (RANS) technique. The radiative transfer equation is solved using a Monte Carlo Method and the Correlated K-distribution (CK) method is used to account for spectral dependency of the absorption coefficient.
