ANSYS Fluent allows anisotropic thermal conductivity for solids but not for fluids. However, certain flows require accounting for non-isotropic thermal conductivity, for example due to the presence of disperse, oriented particles at molecular level. In such situations, it is possible to mimic this effect by introducing a porous media with no drag to modify the effective thermal conductivity. The attached document describes how to setup a simulation to model air flowing through a channel with anisotropic thermal conductivity.
