I implemented these model forms as the divergence terms on the RHS of the scalar T equation. However, the T field is unstable and blows up after about 30 iterations. If anyone has had the experience with these algebraic closures for turbulent heat flux in OpenFOAM, please let me know how you stabilized these models. Thanks.
