This book was released on 1964 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of separated boundary-layer flow was conducted on a two-dimensional flat plate having a variable-span trailing edge flap in the 12-in. Supersonic Tunnel (D) of the von Karman Gas Dynamics Facility. The tests were made at Mach numers 3 and 5 at zero angle of attack and over a Reynolds number range (based on plate length) from 0.26 to 16.7 x 10 to the 6th power. Model surface pressure distributions, schlieren photographs, and velocity distributions are presented. The effects of unit Reynolds number, plate length, flap span, and flap deflection angle on the separated region are investigated, and comparisons are made with existing theory.

Download or read book Separation of Flow written by Paul K. Chang and published by Elsevier. This book was released on 2014-06-28 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interdisciplinary and Advanced Topics in Science and Engineering, Volume 3: Separation of Flow presents the problem of the separation of fluid flow. This book provides information covering the fields of basic physical processes, analyses, and experiments concerning flow separation. Organized into 12 chapters, this volume begins with an overview of the flow separation on the body surface as discusses in various classical examples. This text then examines the analytical and experimental results of the laminar boundary layer of steady, two-dimensional flows in the subsonic speed range. Other chapters consider the study of flow separation on the two-dimensional body, flow separation on three-dimensional body shape and particularly on bodies of revolution. This book discusses as well the analytical solutions of the unsteady flow separation. The final chapter deals with the purpose of separation flow control to raise efficiency or to enhance the performance of vehicles and fluid machineries involving various engineering applications. This book is a valuable resource for engineers.
Download or read book An Investigation on the Laminar Flow Around the Trailing Edge of a Flat Plate written by Ralph Ta-shun Cheng and published by . This book was released on 1967 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of the incompressible fluid motion around a two-dimensional flat plate aligned parallel to the oncoming free stream are thoroughly reviewed and extended. Emphasis is placed on the detailed study of the fluid motion in the neighborhood of the trailing edge. A modified Oseen linearization is used to simplify the Navier-Stokes momentum equations and the stream function equation. These equations are then solved by the Wiener-Hopf technique. The solution of the momentum equations confirms the existence of a singularity at the trailing edge, and the distribution of shear stress on the plate is in agreement with a recent numerical solution. The stream function equation, however, is only formally solved. Finally, an iterative procedure is proposed to solve the viscous fluid motion around an arbitrary two-dimensional finite object. Specifically, the full Navier-Stokes equations are written in the form of inhomogeneous Oseen equations and higher orders of the asymptotic stream function are then determined by solving the inhomogeneous equations with lower order terms substituted in the inhomogeneous part of each of the equations. Green's function is found for the Oseen operator, but no specific example is given in the study. (Author).

This book was released on 2013 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nature has long been an inspiration for research in engineering. In particular, the biological surfaces of aquatic swimmers have been studied for their potential as drag reducing surfaces. The hydrodynamic benefit of riblets, or grooves embedded parallel to the flow, which appear on many aquatic biological surfaces, have been well documented and implemented in practical engineering applications. However the skin of dolphins is embedded with grooves that run perpendicular to the flow of water over their bodies. It is theorized that the transverse grooves present on dolphin skin trap vortices between them, creating a partial slip condition over the surface and inducing turbulence augmentation in the boundary layer, thus controlling boundary layer separation over the dolphin's skin. Similarly, sharks are covered with scales that are flexible at the base and capable of bristling, forming grooves running transverse to the flow. It is theorized that the scales bristle when encountering a reversing flow, thereby trapping vortices between the scales and, similarly, delaying boundary layer separation. In an attempt to test this hypothesis and study these affects, a spinning cylinder was used in a water tunnel to induce separation over a flat plate with 2 mm, rectangular transverse grooves and sinusoidal grooves of similar scaling. The results were compared to tripped, turbulent boundary layer separation occurring over a flat plate without grooves using time-resolved particle image velocimetry. The strength of the adverse pressure gradient was varied, and the observed delay in flow separation and other affects upon the boundary layer are discussed.
