This book was released on 2018-07-16 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed flow field measurements are presented for compressible flow through a diffusing rectangular-to-semiannular transition duct. Comparisons are made with published computational results for flow through the duct. Three-dimensional velocity vectors and total pressures were measured at the exit plane of the diffuser model. The inlet flow was also measured. These measurements are made using calibrated five-hole probes. Surface oil flow visualization and surface static pressure data were also taken. The study was conducted with an inlet Mach number of 0.786. The diffuser Reynolds based on the inlet centerline velocity and the exit diameter of the diffuser was 3,200,000. Comparison of the measured data with previously published computational results are made. Data demonstrating the ability of vortex generators to reduce flow separation and circumferential distortion is also presented.

Book excerpt: An experimental study is conducted to determine the dependence of vortex generator geometry and impinging flow conditions on shed vortex circulation and crossplane peak vorticity for one type of vortex generator. The vortex generator is a symmetric airfoil having a NACA 0012 cross-sectional profile. The vortex generators are mounted either in isolation or in a symmetric counter-rotating array configuation on the inside surface of a straight pipe. The turbulent boundary layer thickness-to-pipe radius ratio is 0.17. Circulation and peak vorticity data are derived from crossplane velocity measurements conducted at or about 1 chord downstream of the vortex generator trailing edge. Shed vortex circulation is observed to be proportional to Mach number, angle of attack and space to boundary-layer thickness. With these parameters held constant, circulation is observed to fall off in monotonic fashion with increasing airfoil aspect ratio. Shed vortex peak vorticity is also observed to be proportional to the aforementioned parameters. Unlike circulation, however, peak vorticity is observed to increase with increasing aspect ratio.
