Book Heat Transfer in Subsonic Separated Flows

Download or read book Heat Transfer in Subsonic Separated Flows written by Viktor I. Terekhov and published by Springer Nature. This book was released on 2022-02-05 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the results of scientific research performed over the past two decades by the authors. The book discusses some issues of separated laminar flows that are of great practical interest for the development of new technologies using microchannel flows, where separation zones can form. Of particular interest is the complex mechanism of flow separation with superimposed high external turbulence. The challenges of finding the optimal location for the cavities and fins on heat exchange surfaces are also considered. This is an important fundamental and practical problem when creating new schemes of efficient heat exchangers in various power plants. A wide class of problems of turbulent flow in tubes with flow separation is considered. These data will be useful in engineering estimates of the thermal–hydraulic efficiency of various heat transfer intensifiers. This book focuses on the analysis of thermal characteristics of separated flows, as well as the possibility of controlling the intensity of heat exchange processes, from the point of view of both their intensification and their suppression.

Book A Theoretical Analysis of Heat Transfer in Regions of Separated Flow

Download or read book A Theoretical Analysis of Heat Transfer in Regions of Separated Flow written by Dean R. Chapman and published by . This book was released on 1956 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flow field analyzed consists of a thin, constant pressure, viscous mixing layer separated from a solid surface by an enclosed region of low-velocity air ("dead air"). The law of conservation of energy is employed to relate calculated conditions within the separated mixing layer to the rate of heat transfer at the solid surface. This physical model is applied to laminar separations in compressible flow for various Prandtl numbers, including consideration of the case where air is injected into the separated region. Application to turbulent separations is made for a Prandtl number of unity in low-speed flow without injection. All calculations are for the case of zero boundary-layer thickness at the position of separation.

Book High Speed Flow Separation Ahead of Finite Span Steps

Download or read book High Speed Flow Separation Ahead of Finite Span Steps written by Louis G. Kaufman and published by . This book was released on 1978 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed surface heat transfer data, oil flow, and schlieren photographs are presented for high speed flow separation ahead of finite span, forward facing steps on flat plates. Step spans were varied from three to ten times as large as the step height, and the step heights are three to four times larger than the undisturbed turbulent boundary layer thickness. Reynolds numbers, based on plate length, were approximately 15 million for both Mach 4.75 and Mach 5.04 local undisturbed flows over the flat plate surface. For these test conditions, the maximum extent of separation ahead of the step is approximately 4.4 times as large as the step height independent of step span, and peak heating rates were measured that are more than six to eight times larger than the undisturbed flow heating rates. Peak heating on the plate surface occurs slightly upstream and approximately 1/2 step height inboard of the outboard sides of the steps; the increase in peak heat transfer coefficients over the undisturbed flow values decreases with increasing step span. In addition to presenting the detailed surface heat transfer data, a plausible theoretical analysis is presented for calculating the region of turbulent boundary layer separation ahead of these finite span steps.

Book Separation of Flow

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.

Book Free Flight Observation of a Separated Turbulent Flow Including Heat Transfer Up to Mach 8 5

Download or read book Free Flight Observation of a Separated Turbulent Flow Including Heat Transfer Up to Mach 8 5 written by Dudley George McConnell and published by . This book was released on 1960 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: A turbulent boundary layer separated by a forward-facing step was observed on the cylindrical portion of a hemisphere-cone-cylinder test vehicle. Tip blunting, producing a shear flow, was found to induce higher pressures on the cylindrical portion than were predicted from ballistic tunnel data of unblunted projectiles. An approximate method for predicting this blunt-body pressure distribution was hypothesized. These findings, along with the hypothesis, were substantiated by a wind tunnel test of a similar body. The peak pressure ratios of the separation were smaller in magnitude than flat plate theory predicted because of the effect of the shear flow. The decrement in heating of the separated flow, relative to the corresponding attached flow, was found to compare well with the expected results.
