Abstract
This chapter introduces the turbulent-viscosity models. In this modelling paradigm the turbulence mechanisms of fluid transport are modelled as a viscous process with the assumption of a turbulent viscosity. The gradient-diffusion hypothesis is at the centre of such modelling paradigm. A series of turbulent-viscosity models are introduced, involving the algebraic models, the Spalart–Allmaras model, the turbulence kinetic energy models, the k − 𝜖 model, and the k − ω model. Finally, turbulent-viscosity models are introduced for the atmospheric boundary layer.
