A Near-Wall Model for Separated Turbulent Flows
1992
A near-wall model for separated turbulent flows is presented and evaluated. The model is bases on experimental obsevations, in particular, the wake-like behavior of turbulence away from walls, the influence of walls on this behavior, the diffusion/dissipation energy balance observed in the backflow portion of detached flow regions, and the near-wall behavior of eddy-viscosity. These lead to two analytically solvable ODE's for the normal-to-wall behavior of turbulence kinetic energy and eddy-viscosity
