Transport-Equation Turbulence Models

Chapter Outline Head

6.1 Introduction

While the zero-equation models discussed in Chapter 5 are useful and accurate for most boundary-layer flows, these models lack generality. For turbulent shear flows other than wall boundary-layers, they require different expressions for mixing length and eddy viscosities. For example, for a plane jet, round jet and plane wake l = 0.09δ, l = 0.07δ, l = 0.16δ, respectively, with δ denoting the shear layer thickness. Transport equation models have less ...
