A turbulent heat flux two-equation $Θ^2 - ε_Θ$ closure based on the V2F 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 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.
