Available in PDF, EPUB and Kindle. Book excerpt: Effects of heat transfer on the separation of laminar boundary layers in supersonic flow are considered theoretically and experimentally. In theory, cooling the wall reduces the extent of regions of separation and steepens the pressure gradients, whilst heating the wall has opposite effects. The experimental results partially confirm these predictions. (Author).

Book excerpt: In 1975 the U.S. Air Force and the Federal Republic of Germany signed a Data Exchange Agreement numbered AF-75-G-7440 entitled 'Viscous and Interacting Flow Fields.' The purpose was to exchange data in the area of boundary layer research. It includes both experimental and theoretical boundary layer research at speeds from subsonic to hypersonic Mach numbers in the presence of laminar, transitional, and turbulent boundary layers. The main effort in recent years has been on turbulent boundary layers, both attached and separated in the presence of such parameters as pressure gradients, wall temperature, surface roughness, etc. In the United States the research was conducted in various Department of Defense, NASA, aircraft corporations, and various university laboratories. In the Federal Republic of Germany it was carried out within the various DFVLR, industrial, and university research centers.

Available in PDF, EPUB and Kindle. Book excerpt: Analytical, numerical, and experimental stndies have documented the flow development and surface heat transfer for several three dimensional end-wall flows, and indicate the presence of highly unsteady vortex formation within the end-wall boundary layer. This vortex formation process leads rapidly to the evolution of three dimensional separation effects which have a profound influence on the surface heat transfer. Analysis of the three dimensional behavior indicates the presence of persistent and strong interactions between the end-wall boundary layers on both the surface and the side-wall boundary layers of the obstacle. A detailed series of Navier-Stokes calculations have been carried out for a vortex-induced motion similar to that encountered in turbulent boundary layers. As the Reynolds number is increased, a new type of instability associated with surface layer separation was found which leads to brealmp of the surface layer. Experimentally, laminar approach flows always develop discrete, periodic necklace vortices in the junction region, whereas a turbulent approach yields a dominant necklace or horseshoe-shaped vortex that moves chaotically. Examinations of the complex fluid/heat transfer processes using PIV and thermochiomic liquid crystals shows that these junction vortices undergo very strong surface interactions, which creates strongly focused "eruptions" of surface fluid; these studies show a direct correlation between the eruptive processes and local regions of high heat transfer.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In the wake of energy crisis due to rapid growth of industries, urbanization, transportation, and human habit, the efficient transfer of heat could play a vital role in energy saving. Industries, household requirements, offices, transportation are all dependent on heat exchanging equipment. Considering these, the present book has incorporated different sections related to general aspects of heat transfer phenomena, convective heat transfer mode, boiling and condensation, heat transfer to two phase flow and heat transfer augmentation by different means.

This book was released on 1961 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Separation caused by the pressure rise induced by flares has been experimentally investigated in the Mach number range of 1.5 to 5.0 and in the Reynolds number range (based on boundary-layer thickness) of 1.5X104 to 12X104. The purpose of the investigation was to determine the model geometry and flow conditions for which separation can be expected for a turbulent boundary layer of zero pressure gradient on the cylinder approaching the flare. Comparisons are made of the boundary-layer-separation characteristics of these three-dimensional flares with two-dimensional separation results from a previous investigation.
