The time averaged Navier-Stokes equations for quasi-steady, axisymmetric, incompressible turbulent flow were solved for an annular geometry. The effects of turbulent interactions are incorporated through the use of two apparent turbulent viscosities which are computed separately for the axial and the tangential momentum equation. Several equations are tested which link the apparent turbulent viscosity in the tangential momentum equation to the tangential velocity profile at each axial location. Best results, as measured by the agreement with experimental data, were obtained with a model that links the viscosity to the tangential velocity via the average flow angle, the wall shear velocity, and the distance of the zero shear location normal to the wall. For four different nominal flow angles at the inlet cross section, the numerical solutions were obtained. Comparisons with experimental data were possible at seven axial locations. The agreement was satisfactory to good in all cases. (Author).

After a brief review of the more popular turbulence models, the author presents and discusses accurate and efficient numerical methods for solving the boundary-layer equations with turbulence models based on algebraic formulas (mixing length, eddy viscosity) or partial-differential transport equations. A computer program employing the Cebeci-Smith model and the k-e model for obtaining the solution of two-dimensional incompressible turbulent flows without separation is discussed in detail and is presented in the accompanying CD.

This book allows readers to tackle the challenges of turbulent flow problems with confidence. It covers the fundamentals of turbulence, various modeling approaches, and experimental studies. The fundamentals section includes isotropic turbulence and anistropic turbulence, turbulent flow dynamics, free shear layers, turbulent boundary layers and plumes. The modeling section focuses on topics such as eddy viscosity models, standard K-E Models, Direct Numerical Stimulation, Large Eddy Simulation, and their applications. The measurement of turbulent fluctuations experiments in isothermal and stratified turbulent flows are explored in the experimental methods section. Special topics include modeling of near wall turbulent flows, compressible turbulent flows, and more.
