This book was released on 2012-12-06 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Physics and Hypersonic Flows bridges the gap between the fluid dynamics and molecular physics communities, emphasizing the role played by elementary processes in hypersonic flows. In particular, the work is primarily dedicated to filling the gap between microscopic and macroscopic treatments of the source terms to be inserted in the fluid dynamics codes. The first part of the book describes the molecular dynamics of elementary processes both in the gas phase and in the interaction with surfaces by using quantum mechanical and phenomenological approaches. A second group of contributions describes thermodynamics and transport properties of air components, with special attention to the transport of internal energy. A series of papers is devoted to the experimental and theoretical study of the flow of partially ionized gases. Subsequent contributions treat modern computational techniques for 3-D hypersonic flow. Non-equilibrium vibrational kinetics are then described, together with the coupling of vibration-dissociation processes as they affect hypersonic flows. Special emphasis is given to the interfacing of non-equilibrium models with computational fluid dynamics methods. Finally, the last part of the book deals with the application of direct Monte Carlo methods in describing rarefied flows.

This book was released on 1968 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the initial interaction of atomic oxygen with various metals in steady flows which provide a step-function increase, or pulse, in the atom concentration. The observations were made by means of thin-film resistance thermometry. The results are presented under three categories as follows: surface recombination efficiencies, atom concentrations, and recombination heat transfer rate.

Download or read book A Method for Determining Catalytic Efficiency of Surfaces written by Ihor O. Bohachevsky and published by . This book was released on 1967 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is described which is used to determine numerically the relationship between the catalytic efficiency (gamma) of a surface and the heat transfer (q) through the surface in low Reynolds number flow of a partially dissociated gas. The work is motivated by the fact that heat transfer is easily measurable in the laboratory whereas catalytic efficiency is not. The approach is directed towards the derivation of a relationship between gamma and the surface concentration of free atoms (c-o); once this relationship is known, it is used to eliminate c-o from the expression relating gamma and q, obtainable from energy balance and from the kinetic theory of gases. To establish the required relationship between gamma and c-o, a mixed boundary value problem for the convective diffusion equation is formulated and solved numerically using an implicit, alternating-direction iteration procedure. The concentration of free atoms is determined not only along the surface, but also throughout the flow field. Results are obtained for a cylinder partially coated with a catalytic substance; they reveal the effect of the velocity field and point out the need for better quantitative knowledge of the low Reynolds number flow. In addition, parameter values for the best experimental accuracy are delineated. (Author).

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.
