## Abstract

A new explicit WET model for the turbulent heat fluxes is derived and developed from the transport equation of the scalar passive flux. In order to study the performance of the model itself, all other turbulent quantities are taken from a DNS channel flow data-base and thus the error source has been minimized. This anisotropic eddy diffusivity model can be solved with a two-equation model for the temperature field based on the temperature variance and its dissipation rate. The model can theoretically be used for a range of Prandtl numbers or a range of different fluids. The results are compared with the DNS channel flow and fairly good agreement is achieved.
