Reynolds-averaged turbulence models are widely used in various engineering fields, with much originality in each field. Specifically, a big difference may be observed between the aeronautical field and the others represented by the mechanical one. The primary features of aeronautical Reynolds-averaged models are linked to the following three points: the coexistence of laminar and turbulent states, the complex ingredients such as density variation, and the high accuracy of computed results required for the design of airfoils etc. In this article, detailed discussions are made about the physical meaning of the Baldwin-Lomax (zero-equation) model, the Sparart-Allmaras (one-equation or turbulent-viscosity transport-equation) model, and the Menter (two-equation) model. The present article aims at understanding their essence from a physical viewpoint based on time scales.
