Hello everyone, I'm working on an algebraic turbulent heat flux model for low Prandtl number fluids. Currently, some of the literature I've investigated uses OPENFOAM or STAR CCM+, and no one uses FLUENT to implement this model. In Ansys Fluent, turbulent heat transport is modeled using the concept of Reynolds’ analogy to turbulent momentum transfer. The "modeled" energy equation is therefore given by: For the standard and realizable k-e models, the effective thermal conductivity is given by: In the literature I researched, the Reynolds-averaged energy equation can be written as: And the temperature flux model is based on an algebraic formulation for the turbulent heat flux and is given as: How can I change in FLUENT to implement an algebraic turbulent heat flux model? Thank you sincerely. |
