Book Experimental Investigation of the Turbulent Large Scale Temporal Flow in the Wing Body Junction

Download or read book Experimental Investigation of the Turbulent Large Scale Temporal Flow in the Wing Body Junction written by E. P Rood (Jr) and published by . This book was released on 1984 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of the fluid dynamic flow in the wing-body junction was made to reveal the existence of large scale, time-dependent structures. These temporal features are discussed relative to the three major parts of the mean flow: the onset boundary layer, the wing-body junction flow characterized by the horseshoe root vortex, and the wing-body junction wake flow. Distinct flow structures, distinguished by bandwidths, were observed in all parts of the flow. One type of structure was due to the distortion of the existing structure of the onset boundary layer by the wing. A second and a third structure were newly created in the flow by the presence of the wing. These unique structures along the body were boundary layer phenomena, clearly distinguishable from ordinary Strouhal-type shedding at the wing trailing edge. The measurements distinguishing the structures were made using applications of two-point spectral correlation analyses of the flow velocities. The application of this estbalished procedure was made possible by modern high speed data techniques. An orderly framework of definitions and discussion is presented around which additional research can be performed to discover the details of the flow structure. (Author).

Book Theoretical and Experimental Investigation of Flow Over Single and Double Backward Facing Steps

Download or read book Theoretical and Experimental Investigation of Flow Over Single and Double Backward Facing Steps written by Stanford University. Thermosciences Division. Thermosciences Division and published by . This book was released on 1961 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: A semi-empirical analysis is developed for the over-all flow pattern of subsonic turbulent flow over backward facing steps. Good agrement is found between theory and experiment for the prediction of two-dimensional reattachment length for small values of step height to throat width ratio; an asymptotic solution for large values of step height is also given and discussed. Mean velocity profiles calculated by the present analysis are shown; they require an empirical fit at one point. Good agreement with experiment is found in the region near the step face, but agreement is poor near the reattachment region. Experimental results are represented for flow patterns over backward facing steps covering a wide range of geometric variables. Velocity profile measurements are given for both single and double steps. The stall region is shown to consist of a complex pattern involving three distinct regions. The double step contains an asymmetry for large expansions, but approaches the single-step configuration with symmetric stall regions for small values of area ratio. No effect on flow pattern or reattachment length is found for a wide range of Reynolds numbers and turbulence intensities, provided the flow is fully turbulent before the step. (Author).
