Dear formers,
The built-in openfoam turbulence models solve for homogenous eddy viscousity coefficients, that is, they are the same in the three directions with Nut_x=Nut_y=Nut_z. However, in my concerned problem, the eddy viscosity coefficients are apparently nonhomogenous with Nut_x=Nut_y>>Nut_z, and they are the functions of velocity gradients and temperature gradients.
But, I really have no idea of how to implement this turbulence model. Shall someone give me some advice or instruction? I will be highly appreciated for any help!
Merry Chrismas to all!
