Testing of RANS Turbulence Models for Stratified Flows Based on DNS Data

Abstract

Stably stratified flows such as those in the atmosphere or in large water bodies such as the ocean, lakes, estuaries and reservoirs are prevalent in the natural environment. The presence of the buoyancy force due to the stratification may have a substantial effect on the flow development and mixing processes, and hence influence the distribution of scalar substances such as pollutants, suspended sediments, in the environment.
