A methodology to predict OH* radiation in turbulent diffusion flames for rocket engine applications with low numerical cost is presented. On the basis of an extended flamelet approach including the OH* species, a RANS combustion simulation for the single injector configuration Mascotte at 60 bar is conducted. For the comparison of the numerical results with experimental radiation data, self-absorption of OH* is accounted for in a post-processing step as well. Results show that the OH* radiation is well reproduced and the consideration of both turbulence-chemistry interaction as well as self-absorption is essential. It is also shown that OH* radiation should not be used to quantify the spatial distribution of the volumetric heat release rate.
