The feature of Reynolds heat flux model is to close Eq. (2.3a) by solving —u [T directly. Similar to the derivation of Reynolds stress equation, the u jT equation can be obtained as follows ... 

The standard Rayleigh heat flux model equations are as follows ... 

The algebraic model equations are similar to the standard Reynolds heat flux model except using Eq. (2.14) to replace Eq. (2.13) for reducing the computer load. 

Reynolds heat flux model, in which the unknown —pu T is calculated directly using its modeled Eq. (2.13). Although the computer load is increased, it is rigorous and anisotropic. The Algebraic Reynolds heat flux model as given by Eq. (2.14) is the simplified form. 

The film theory describes heat transfer to the surface. The heat flux modeled using the heat transfer coefficient is balanced with the flux into the solid sphere ... 

The Fourier heat flux model under macroscopic continuum formulation is given as...
