### Abstract

A direct numerical simulation (DNS) of the instantaneous Navier-Stokes equation and the continuity equation provides a means to understand low Reynolds number turbulent flows of single-phase, Newtonian fluids in simple geometries. The ensemble average of these two equations yields the unclosed RANS-equation and the average continuity equation. Clearly, an appropriate closure model for the Reynolds stress is needed to support simulations of the RANS-equation for high Reynolds number flows in complex geometries.
