This book was released on 1977 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical solutions of the Navier-Stokes equations are obtained and results presented for conical diffuser flows with turbulent nonuniform inlet conditions. The turbulent flow field is described by a two-equation, low-Reynolds-number k-epsilon model with a new turbulence model for axisymmetric flow. Fast convergence is achieved with an improved initial flow-field guess and a multiple grid Gauss-Seidel iteraction method. Comparisons are made with existing data for several diffuser divergence angles with and without flow separation. Good agreement was obtained between theory and experiment. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A general finite difference formulation of the incompressible Navier-Stokes equations in terms of the vorticity and the stream function is presented for turbulent internal flows. Turbulent models such as algebraic eddy viscosity models, and the low Reynolds number two-equation k-epsilon models were systematically studied. Numerical solutions are presented for both separated and non-separated subsonic diffuser flows with either a sublayer coordinate stretching or a low of the wall matching procedure. Excellent agreement with experimental data is obtained for the fully developed channel flow. Agreement with data from an 8-deg conical diffuser is also good. The detailed flow-field structure for separated diffuser flows can be obtained including the prediction of the separation point. (Author).
