Download or read book Numerical Computation of Subsonic Conical Diffuser Flows with Nonuniform Turbulent Inlet Conditions written by and published by . This book was released on 1977 with total page 0 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).

Download or read book Prediction of Transitory Stall in Two dimensional Diffusers written by S. Ghose and published by . This book was released on 1976 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program has been developed that predicts the performance of diffusers operating in the transitory stall region, including the region of optimum recovery at fixed length. Results agree with data to the uncertainty in existing data. The important changes in method that underlie this advance are two: (i) simultaneous calculation of the outer flow and the separating layer which eliminates singular behavior in the zone of flow detachment; (ii) an improved boundary layer method that adequately approximates backflows near the wall and also represents both attached and free shear layers with good accuracy; the method employs Bradshaw's entrainment-shear miximum correlation, which is shown to hold over an extended range of flow conditions. Comparisons of the boundary layer scheme with the data of the 1968 Conference on Computation of Turbulent Boundary Layers and with the separating flow data of Strickland and Simpson both show good agreement in H, delta(*), C sub f/2.

Download or read book Numerical Analysis of Turbulent Separated Subsonic Diffuser Flows written by J. C. Chien and published by . This book was released on 1977 with total page 164 pages. 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).

This book was released on 2003-09-01 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical study on laminar incompressible flows in 2-D straight walled diffusers in the low Reynolds number regime (105-1048) is presented to investigate performance and various flow regimes that might exist. Tail channels are situated downstream the diffusers. Geometries with area ratios AR-=1.15 to 5 and non-dimensional lengths of L/W1=1 to 48 are considered. Results are presented in terms of flow regime maps for Reynolds numbers of 105, 210, 314, 420, 629, 1,048 and pressure recovery coefficients maps for Re numbers of 105, 210, 314, 420 and 629. In addition time resolved simulations of impulsively starting flow are considered at Re=210, 314 for 12 geometries on the flow regime map. Four flow regimes can be distinguished depending on diffuser geometry. With increasing divergence angle the flow goes from attached to symmetrically separated to asymmetrically separated and finally to a non 2-D pattern respectively.
