Book Description
The problem of the turbulent mixing along the curved boundaries of a jet has been analyzed for an incompressible plane flow. The initial and fully developed regions of the curved mixing zone are analyzed with Tollmien and Goertler eddy viscosity models. It is shown that similarity solutions exist under certain conditions. A perturbation analysis is carried out to include the first order effects of curvature and growth of mixing zone. Comparison is made of the results of the numerical computation with the two eddy viscosity models. A parametric study of different centerline velocity decay rates and the external pressure gradient is made in the fully developed region.

Book Description
A numerical investigation is reported of turbulent incompressible jets confined in two ducts, one cylindrical and the other conical with a 5 degree divergence. In each case, three Craya-Curtet numbers are considered which correspond, respectively, to flow situations with no moderate and strong recirculation. Turbulence closure is achieved by using the k-epsilon model and a recently proposed realizable Reynolds stress algebraic equation model that relates the Reynolds stresses explicitly to the quadratic terms of the mean velocity gradients and ensures the positiveness of each component of the turbulent kinetic energy. Calculations are carried out with a finite-volume procedure using boundary-fitted curvilinear coordinates. A second-order accurate, bounded convection scheme and sufficiently fine grids are used to prevent the solutions from being contaminated by numerical diffusion. The calculated results are compared extensively with the available experimental data. It is shown that the numerical methods presented are capable of capturing the essential flow features observed in the experiments and that the realizable Reynolds stress algebraic equation model performs much better than the k-epsilon model for this class of flows of great practical importance.
