Abstract

This chapter presents the simplest way to handle the Reynolds-averaged Navier–Stokes (RANS) equations by using the Boussinesq approximation to close the system of equations. We also present a wide variety of turbulence models that can be employed using the Boussinesq approximation. It is shown that though this assumption involves major simplification, it leads to fairly accurate predictions in many simple situations. Some such situations are illustrated in this chapter.
