Application of the Governing Equations to Turbulent Flow

Abstract

To quantitatively describe and forecast the state of the boundary layer, we turn to the equations of fluid mechanics that describe the dynamics and thermodynamics of the gases in our atmosphere. Motions in the boundary layer are slow enough compared to the speed of light that the Galilean/Newtonian paradigm of classical physics applies. These equations, collectively known as the equations of motion, contain time and space derivatives that require initial and boundary conditions for their solution.
