Zero-thermal dispersion conductivity
Description
Most macroscale models neglect thermal dispersion Suikkanen et al. (2014) and Li and Ji (2016), in which case is given as
(1)
Neglecting thermal dispersion is expected to be a reasonable approximation for high Reynolds numbers Gunn (1978) and Littman et al. (1968), but for low Reynolds numbers more sophisticated models should be used Becker and Laurien (2002). Because thermal dispersion acts to increase the diffusive effects, neglecting thermal dispersion is (thermally) conservative in the sense that peak temperatures are usually higher Becker and Laurien (2002).
