The paper deals with the implementation of two-equation turbulent heat flux closures in the form proposed by Abe et al. and Deng et al., combined with the second order turbulence model for momentum field for gas cooling application. Implemented models have been compared with the experimental data by Gartshore et al. and Kohli et al. concerning the flat plate cooling with a compound angle orientation. It has also been compared with the standard solution of turbulent heat flux by means of a constant and variable turbulent Prandtl number.
