 Abstract

A k-model is formulated that consists of the turbulent kinetic energy equation and an algebraic expression for the mixing length taking into account the influence of stratification. Applicability of the model is restricted to shallow, nearly horizontal flows. For local-equilibrium flows the model reduces to the well-known mixing-length hypothesis including a damping function depending on the gradient Richardson number. The model is applied to stratified turbulent Poiseuille flow between two parallel plates.
