A new k-E model is introduced that is consistent with Monin-Obukhov similarity theory (MOST). The proposed k-E model is compared with another k-E model that was developed in an attempt to maintain inlet profiles compatible with MOST. It is shown that the previous k-E model is not consistent with MOST for unstable conditions, while the proposed k-E model can maintain MOST inlet profiles over distances of 50km.
