kakkapriyesh is on a distinguished road

I had modified the OpenFOAM solver to see the effects of turbulent Prandtl numbers on the heat transfer near the wall (dynamic Smagorinsky | LES). For incompressible solver, OpenFOAM keeps turbulent Prandtl number as constant, hence energy equation solved is not truly dynamic. I calculated turbulent Prandtl number using test filters similar to dynamic models referring to Lilly's paper of 1992. Here, the turbulent Prandtl number is calculated at every timestep, and it influences the energy equation.

Please find the solver Github link for more details:

I hope this code is useful to someone!
