This book was released on 2018-11-02 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: An efficient steady analysis for predicting strong inviscid/viscid interaction phenomena such as viscous-layer separation, shock/boundary-layer interaction, and trailing-edge/near-wake interaction in turbomachinery blade passages is needed as part of a comprehensive analytical blade design prediction system. Such an analysis is described. It uses an inviscid/viscid interaction approach, in which the flow in the outer inviscid region is assumed to be potential, and that in the inner or viscous-layer region is governed by Prandtl's equations. The inviscid solution is determined using an implicit, least-squares, finite-difference approximation, the viscous-layer solution using an inverse, finite-difference, space-marching method which is applied along the blade surfaces and wake streamlines. The inviscid and viscid solutions are coupled using a semi-inverse global iteration procedure, which permits the prediction of boundary-layer separation and other strong-interaction phenomena. Results are presented for three cascades, with a range of inlet flow conditions considered for one of them, including conditions leading to large-scale flow separations. Comparisons with Navier-Stokes solutions and experimental data are also given. Barnett, Mark and Verdon, Joseph M. and Ayer, Timothy C. Unspecified Center NAS3-25425; RTOP 584-03-11...

Available in PDF, EPUB and Kindle. Book excerpt: A numerical solution procedure capable of a high degree of automation is presented for calculating the flow field associated with viscid-inviscid interaction on a body of revolution. The method makes use of ideas from asymptotic triple deck analysis of the trailing edge problem. A simpler problem is solved in which two layers are postulated, an outer inviscid, rotational layer (frozen vorticity) which largely governs the pressure in the trailing edge region, and an inner turbulent layer which is modeled in a simple manner. These two layers are patched at a fixed distance from the wall and wake centerline rather than asymptotically matched. The method allows the viscid-inviscid interaction solution to be computed in four interactions, none of which require any user intervention. A high degree of automation is achieved in the computer code because of three factors: (1) the solution cycle is very stable, (2) all calculations use a common streamwise grid, and (3) information is transferred to successive stages of the calculation by computer generated files. Numerical solutions are presented for three bodies and the results compared with published experimental data.

Available in PDF, EPUB and Kindle. Book excerpt: A viscous inviscid interaction method for three dimensional flows, in which the partially parabolic Reynolds equations are coupled with an inviscid flow solution procedure in an interactive and iterative manner, is applied to two simple three dimensional bodies for which experimental data are available for comparison. The relative merits of interactive and global solution procedures are evaluation by comparing the viscous inviscid interaction solutions with noninteractive large domain solutions of only the viscous flow equations. Both methods yield satisfactory results, although the interaction solutions are found to be computationally more efficient for the cases considered.

Download or read book An Axisymmetric Strong Interaction Procedure to Include Large Normal Pressure Gradients written by M. S. Dietz and published by . This book was released on 1980 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a modified strong-interaction procedure for axisymmetric bodies. The modifications include the addition of the normal momentum equation to the boundary-layer calculations and the patching of the viscous-inviscid flow solutions at the boundary-layer edge to account for large, normal pressure gradients. The resulting weakly elliptic problem is solved by an iterative technique. Based on results to date, the use of an under-relaxation factor and some smoothing are required to obtain a converged solution. (Author).
