Available in PDF, EPUB and Kindle. Book excerpt: Direct heat addition of flowing gases by radiation absorption is considered. In the Infrared regime, the coupling between a laser beam ad a flowing gas is being modeled numerically. Implicit time iterative procedures originally developed for transonic flows are being adapted to the low Mach number, low Reynolds number regimes of interest. Two dimensional solutions show that absorption plasmas can exist over a wide range of flow speeds and that buoyancy can be a dominant factor when the forced convection velocity is small. In the microwave regime, an experimental investigation of various absorption modes is underway. An overview of the experimental design and initial experimental results is presented. Numerical predictions of the resonant cavity and propagating plasma modes of microwave absorption are also discussed. Keywords: Laser gas dynamic interaction; microwave heating of gases; Beamed energy; Advanced propulsion.

Available in PDF, EPUB and Kindle. Book excerpt: When the temperature of a gas is not too high and the density of a gas is not too low, the transfer of heat by radiation is usually negligibly small in comparison with that by conduction and convection. However, in the hypersonic flow of space flight, particularly in the re-entry of a space vehicle, and in the flow problem involving nuclear reaction such as in the blast wave of nuclear bomb or in the peaceful use of the controlled fusion reaction, the temperature of the gas may be very high and the density of the gas may be very low. As a result, thermal radiation becomes a very important mode of heat transfer. A complete analysis of such high temperature flow fields should be based upon a study of the gasdynamic field and the radiation field simultaneously. Hence during the last few years, considerable efforts have been made to study such interaction problems between gasdynamic field and radiation field and a new title, Radiation Gasdynamics, has been suggested for this subject. Even though radiative transfer has been studied for a long time by astro physicists, the interaction between the radiation field and the gadsynamic field has been only extensively studied recently.

Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, the rapid growth of knowledge in the field of fluid mechanics and heat transfer has resulted in many significant ad vances of interest to students, engineers, and scientists. Accordingly, a course entitled "Modern Developments in Fluid Mechanics and Heat Transfer" was given at the University of California to present significant recent theoretical and experimental work. The course consisted of seven parts: I-Introduction; II-Hydraulic Analogy for Gas Dynamics; 111- Turbulence and Unsteady Gas Dynamics; IV-Rarefied and Radiation Gas Dynamics; V-Biological Fluid Mechanics; VI-Hypersonic and Plasma Gas Dynamics; and VII-Heat Transfer in Hypersonic Flows. The material, presented by the undersigned as course instructor and by various guest lecturers, could easily be adapted by other universities for use as a text for a one-semester senior or graduate course on the subject. Due to the extensive notes developed during the University of California course, it was decided to publish the material in three volumes, of which the present is the first. The succeeding volumes will be entitled "Selected Topics in Fluid and Bio-Fluid Mechanics" and "Introduction to Steady and Unsteady Gas Dynamics." Finally, I must express a word of appreciation to my wife Irene and to my children, Wellington Jr. and Victoria, who made it possible for me to write and edit this book in the very quiet atmosphere of our home.

Available in PDF, EPUB and Kindle. Book excerpt: High Temperatures in Aeronautics is a compilation of the proceedings of the Symposium on High Temperatures in Aeronautics held in Turin, Italy, on September 10-12, 1962. The symposium provided a forum to discuss the applications of high temperatures in aeronautics and covers topics ranging from supersonic combustion to non-equilibrium flow through a nozzle, along with similarity parameters in radiation gas-dynamics and photoionization upstream of a strong shock wave. This volume is comprised of 17 chapters and begins with an overview of the effects and consequences of high temperature in aeronautics, followed by an analysis of experimental results for the dissociation of diatomic gases. A theoretical and experimental investigation of mixing and supersonic combustion is then presented, focusing on inviscid flow fields with a finite rate chemistry for a hydrogen-air reaction. Turbulent mixing for flows with large density gradients having no chemical reaction is also considered, and the results of experiments in supersonic combustion are discussed. Subsequent chapters deal with silicon nitride, its properties, and its potential use at elevated temperatures; materials problems at high temperature; and the corrosion of refractory alloys by oil ash containing vanadium. This monograph will be of interest to students, engineers, and experimental workers in the fields of astronautics and aeronautical engineering.

This book was released on 1968 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical model for the interaction of radiative and vibrational rate processes in the flow of an infrared-active diatomic gas is developed, with specific application to radiative acoustics and to flow through a normal shock wave. Macroscopic equations of radiative transfer and vibrational relation are obtained, that, while retaining the essential features of the microscopic physics, are simple enough to incorporate usefully with the conservation equation of gas dynamics. The transfer equation is linearized about an equilibrium reference state in a plane-parallel geometry. The analysis is then able to retain the essentially nongrey spectral character of the radiative field because the linearization allows the integration over spectral frequency to be carried out independently of the integrations over space. For application in acoustics, the foregoing results are combined with the linearized vibrational rate equation and linearized equations of unsteady, inviscid flow. This leads to a single, sixth-order acoustic equation for a radiating, relaxing gas, which contains the earlier equations for vibrational or radiative nonequilibrium alone as special cases. The consequences of coupling between radiative and molecular nonequilibrium are explored in detail by an analytical, perturbation solution for the flow through a normal shock wave. The relative importance of the radiative process for a given shock strength and upstream temperature increases with decreasing upstream pressure. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The following text forms the proceedings of a conference. It is supposed to contain what was actually reported and discussed, though it does this, one hopes, in a polished and organized way. A sense of actuality, a reporting quality, makes this book different from a collection of review papers as, for example, a book in the series on Stars and Stellar Systems. All Invited Reports have been included as the Reporters wrote them. The Editor's task has been restricted to improving the presentation, a process which in most cases involved only minor revisions. In a few Reports the Editor did some heavy rewriting; in those cases he checked with the Reporters. Obviously a different course had to be taken with respect to the Discussions. They were recorded on tape, transcribed verbatim and then passed back to the discussants. After the discussants returned their versions, the Editor rearranged and condensed the texts and made a considerable effort to provide references. (Unfortunately he was not able to locate all relevant Russian papers from 1968 and 1969. ) The Editor takes the responsibility for mistakes made in this process, which may have produced occasionally his own 'mix-master Universe'. Actually only a few discussion remarks were rejected, more often because of incomprehensibility, rather than because the remark was far from the subject of the Symposium, or was too long, or was too trivial. A few very long remarks have been condensed and put at the end of a Discussion.
