Abstract

Many turbulence models have been invalidated by the complex structure of wall turbulent flows that exhibit separation, swirl or low-Reynolds number effects. This paper, introduces some of the various attempts that have been made to model turbulence in an endeavour to improve numerical predictions of wall turbulent flows. Emphasis is given to the k- ε model of turbulence which is the most extensively used and accepted model today. Furthermore, the improvements made to the wall functions that are coupled with the standard k-ε model, and the nonisotropic effects taken on the eddy viscosity near walls have been discussed, and the various modifications applied to the k-e model that refer to low Reynolds number effects reviewed. In addition, the range of applicability of some of the other models having importance to wall shear flows has been pointed out. The wall functions in conjunction with the standard k-e model provide computational expediency and economy, while the low-Reynolds number k-e forms numerically reproduce wall turbulent flows more closely.
