Available in PDF, EPUB and Kindle. Book excerpt: Stagnation-point heat transfer to two- and three-dimensional bodies at low Reynolds numbers was studied to obtain hypersonic low-density data and to demonstrate the suitability of the hypersonic shock tunnel as a facility for research in rarefied gasdynamics. Low-density experiments on a transverse cylinder and a hemisphere cylinder were made in air at Mach numbers from 8.4 to 11.6 in the CAL 11- by 15-inch hypersonic shock tunnel. The stagnation pressure and temperature, as well as model diameter, were varied to obtain a range of Reynolds numbers from 11 to 1000, based on flow conditions behind the bow shock wave and model radius. The experimental heat-transfer rates are presented and compared with theoretical predictions. The data obtained with the transverse cylinders are in good agreement with continuum boundary-layer theory at all but the lowest Reynolds numbers and highest Knudsen numbers. The hemisphere-cylinder data indicated the presence of a significant vorticity-interaction effect. Good agreement with the theoretical analysis of H.K. Cheng accounting for this effect is indicated.

Book Synopsis Experimental Heat Transfer to Blunt Axisymmetric Bodies Near the Limit of Continuum Flow by : J. Leith Potter
Download or read book Experimental Heat Transfer to Blunt Axisymmetric Bodies Near the Limit of Continuum Flow written by J. Leith Potter and published by . This book was released on 1962 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of average heat-transfer rates to blunt-nosed, axisymmetric, cold-walled bodies in a low-density, hypervelocity wind tunnel are given. Stream density was such that Reynolds and Knudsen numbers, based on nose radius and conditions immediately behind the bow shock, varied from 5 to 20 and 0.11 to 0.056, respectively. Thus, scaling on the basis of Knudsen number, these conditions may be said to simulate a body of one-foot nose radius at as much as 315,500-ft altitude. Heat-transfer rates are discussed in relation to the flow model successfully used in the past for studies of flows of high Reynolds number. In this context, it was found that measured heat-transfer rates to hemispheres below shock-layer Reynolds numbers of 20 exhibited a decreasing nondimensionalized rate relative to that estimated by methods appropriate to high Reynolds number conditions. This behavior is in accord with various applicable theories. Rates for the flat-faced bodies showed no tendency to decrease, and they were somewhat higher than predicted by theories for high Reynolds numbers.
Book Synopsis Theoretical Modelling of Aeroheating on Sharpened Noses Under Rarefied Gas Effects and Nonequilibrium Real Gas Effects by : Zhi-Hui Wang
Download or read book Theoretical Modelling of Aeroheating on Sharpened Noses Under Rarefied Gas Effects and Nonequilibrium Real Gas Effects written by Zhi-Hui Wang and published by Springer. This book was released on 2014-08-28 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical Modelling of Aeroheating on Sharpened Noses under Rarefied Gas Effects and Nonequilibrium Real Gas Effects employs a theoretical modeling method to study hypersonic flows and aeroheating on sharpened noses under rarefied gas effects and nonequilibrium real gas effects that are beyond the scope of traditional fluid mechanics. It reveals the nonlinear and nonequilibrium features, discusses the corresponding flow and heat transfer mechanisms, and ultimately establishes an analytical engineering theory framework for hypersonic rarefied and chemical nonequilibrium flows. The original analytical findings presented are not only of great academic significance, but also hold considerable potential for applications in engineering practice. The study explores a viable new approach, beyond the heavily relied-upon numerical methods and empirical formulas, to the present research field, which could be regarded as a successful implementation of the idea and methodology of the engineering sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Theory and Fundamental Research in Heat Transfer focuses on the processes, methodologies, reactions, and mechanisms involved in heat transfer. The selection first offers information on thermal radiation characteristics of surfaces, including intensity of radiation, intensity of emission and angular emittance, reflectance relationships, diffuse reflector, hemispherical and total reflectances, reflectivity of homogeneous isotropic polished surfaces, and angular total remittance measurements. The text then takes a look at heat transfer in rarefied gas flow, as well as accommodation coefficient and free molecule transfer, near free molecule heat transfer, continuum heat transfer regimes, and transitional regime. The publication ponders on boiling heat transfer and plasma heat transfer. Turbulent heat transfer in stratified flow, thermal conductivity of solids, and studies on quantitative spectroscopy and gas emissivities are also discussed. Topics include emissivity calculations, mechanisms of thermal conductivity, and conductivity at low and intermediate temperatures. The selection is a dependable reference for readers interested in the processes, reactions, and mechanisms involved in heat transfer.

Book Synopsis Hypersonic and High Temperature Gas Dynamics by : John David Anderson
Download or read book Hypersonic and High Temperature Gas Dynamics written by John David Anderson and published by AIAA. This book was released on 1989 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a self-contained text for those students and readers interested in learning hypersonic flow and high-temperature gas dynamics. It assumes no prior familiarity with either subject on the part of the reader. If you have never studied hypersonic and/or high-temperature gas dynamics before, and if you have never worked extensively in the area, then this book is for you. On the other hand, if you have worked and/or are working in these areas, and you want a cohesive presentation of the fundamentals, a development of important theory and techniques, a discussion of the salient results with emphasis on the physical aspects, and a presentation of modern thinking in these areas, then this book is also for you. In other words, this book is designed for two roles: 1) as an effective classroom text that can be used with ease by the instructor, and understood with ease by the student; and 2) as a viable, professional working tool for engineers, scientists, and managers who have any contact in their jobs with hypersonic and/or high-temperature flow.

Download or read book Advances in Hypersonics written by BALLMAN and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: These three volumes entitled Advances in Hypersonics contain the Proceedings of the Second and Third Joint US/Europe Short Course in Hypersonics which took place in Colorado Springs and Aachen. The Second Course was organized at the US Air Force Academy, USA in January 1989 and the Third Course at Aachen, Germany in October 1990. The main idea of these Courses was to present to chemists, com puter scientists, engineers, experimentalists, mathematicians, and physicists state of the art lectures in scientific and technical dis ciplines including mathematical modeling, computational methods, and experimental measurements necessary to define the aerothermo dynamic environments for space vehicles such as the US Orbiter or the European Hermes flying at hypersonic speeds. The subjects can be grouped into the following areas: Phys ical environments, configuration requirements, propulsion systems (including airbreathing systems), experimental methods for external and internal flow, theoretical and numerical methods. Since hyper sonic flight requires highly integrated systems, the Short Courses not only aimed to give in-depth analysis of hypersonic research and technology but also tried to broaden the view of attendees to give them the ability to understand the complex problem of hypersonic flight. Most of the participants in the Short Courses prepared a docu ment based on their presentation for reproduction in the three vol umes. Some authors spent considerable time and energy going well beyond their oral presentation to provide a quality assessment of the state of the art in their area of expertise as of 1989 and 1991.

This book was released on 2013-10-22 with total page 773 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in International Research on Thermodynamic and Transport Properties covers the proceedings of the 1962 Second Symposium by the same title, held at Purdue University and the Thermophysical Properties Research Center. This symposium brings together theoretical and experimental research works on the thermodynamic and transport properties of gases, liquids, and solids. This text is organized into nine parts encompassing 68 chapters that cover topics from thixotropy to molecular orbital calculations. The first three parts review papers on theoretical, experimental, and computational studies of the various aspects of thermodynamic properties. These parts discuss the principles of phase equilibria, throttling, volume heat capacity, steam, volumetric behavior, enthalpy, and density. The subsequent part highlights the theoretical evaluations of transport properties, such as viscosity, diffusion, and conductivity, as well as the transport processes. These topics are followed by surveys of the theories in intermolecular forces and their applications. Other parts consider the measurement of thermal conductivity, viscosity, and radiation. The final parts examine the properties of ionized gases and non-Newtonian fluids. This book will prove useful to mechanical and chemical engineers.
