This paper deals with the problem of turbulent heat transfer modeling based on the exact transport equations for the second and third order correlation moments. The effects of rotation and stratification are included. The suitable equations are derived, some for the first time. The closure methods for these equations are discussed and the new approach to modelling of triple correlations the correlation of the velocity actuation with the autocorrelation of the temperature) is presented.

The paper deals with the proposition of a two-equation turbulent heat flux closure without any damping function. The model has been based on Durbin's V2F dynamic turbulence closure and the Deng-Wu-Xi thermal turbulence model. Both models have been implemented into the FLUENT code by a User Defined Function. Results of numerical computation have been compared with experimental data for developing a thermal field in a pipe by Nagano and DNS heat transfer prediction for a two-dimensional channel flow by Kasagi.
