A TURBULENT HEAT FLUX TWO–EQUATION θ 02 –εθ CLOSURE BASED ON THE V 2F TURBULENCE MODEL
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 V 2F 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.
Keywords:turbulent heat transfer, turbulent Prandtl number, low-Reynolds-number models, Durbin’s model of turbulence
