Abstract

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