Available in PDF, EPUB and Kindle. Book excerpt: Summary: The deceleration of air from supersonic velocities in channels has been studied. It has become apparent that a normal shock in the diverging part of the diffuser is probably necessary for stable flow, and ways of minimizing the intensity of this shock have been developed. The effect of various geometrical parameters, especially contraction ratio in the entrance region, on the performance of supersonic diffusers has been investigated. By the use of these results, diffusers were designed which, starting without initial boundary layer, recovered 90 percent of the kinetic energy in supersonic air streams up to a Mach number of 1.85.

This book was released on 1951 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted in the Lewis 4- by 4-inch variable Mach number tunnel to determine off-design internal performance of three types of supersonic diffuser. Results were obtained at Mach numbers ranging from 1.75 to 2.74 with a normal-shock diffuser, two single-shock spike diffusers designed for Mach numbers 1.75 and 2.40, respectively, and tree convergent-divergent perforated diffusers designed for Mach numbers 1.75, 2.10, and 2.50, respectively. The variation of total-pressure recovery with relative mass flow was determined at various Mach numbers in the range. A thrust coefficient based on these measurements was utilized to facilitate interpretation of the results.

Available in PDF, EPUB and Kindle. Book excerpt: A revised edition to applied gas dynamics with exclusive coverage on jets and additional sets of problems and examples The revised and updated second edition of Applied Gas Dynamics offers an authoritative guide to the science of gas dynamics. Written by a noted expert on the topic, the text contains a comprehensive review of the topic; from a definition of the subject, to the three essential processes of this science: the isentropic process, shock and expansion process, and Fanno and Rayleigh flows. In this revised edition, there are additional worked examples that highlight many concepts, including moving shocks, and a section on critical Mach number is included that helps to illuminate the concept. The second edition also contains new exercise problems with the answers added. In addition, the information on ram jets is expanded with helpful worked examples. It explores the entire spectrum of the ram jet theory and includes a set of exercise problems to aid in the understanding of the theory presented. This important text: Includes a wealth of new solved examples that describe the features involved in the design of gas dynamic devices Contains a chapter on jets; this is the first textbook material available on high-speed jets Offers comprehensive and simultaneous coverage of both the theory and application Includes additional information designed to help with an understanding of the material covered Written for graduate students and advanced undergraduates in aerospace engineering and mechanical engineering, Applied Gas Dynamics, Second Edition expands on the original edition to include not only the basic information on the science of gas dynamics but also contains information on high-speed jets.

This book was released on 1966 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of missile and nuclear weapons systems are presented in this book which is primarily prepared as the second text of a three-volume series for students of the Navy Reserve Officers' Training Corps and the Officer Candidate School. Following an introduction to guided missiles and nuclear physics, basic principles and theories are discussed with a background of the factors affecting missile flight, airframes, missile propulsion systems, control components and systems, missile guidance, guided missile ships and systems, nuclear weapons, and atomic warfare defense. In the area of missile guidance, further explanations are made of command guidance, beam-rider methods, homing systems, preset guidance, and navigational guidance systems. Effects of nuclear weapons are also described in categories of air, surface, subsurface, underwater, underground, and high-altitude bursts as well as various kinds of damages and injuries. Besides illustrations for explanation purposes, a table of atomic weights and a glossary of general terms are provided in the appendices.

This book was released on 1983 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unsteady, compressible, Reynolds-averaged Navier-Stokes equations were solved for the flow field about an external compression axi-symmetric inlet with a length to diameter ratio, L/D = 15.88, at Mach 2.0 and a Reynolds number based on diameter, ReD = 2.36 times 10 to the 6th power, operating in the near-critical and subcritical flow regimes. The near-critical solution reached a stable steady state while the subcritical solutions attained an unstable bounded oscillatory state, characterized by large amplitude pressure oscillations and traveling shock waves. This phenomenon is a result of a shear layer instability combined with a closed-loop feedback of reflected disturbances and the naturally occurring self-sustained oscillations are commonly known as buzz. Numerical results are given in terms of Mach contours, velocity field plots, pressure-time traces at selected stations, as well as mass flux and other mass-averaged quantities along the duct length. Comparison with experiment is also given. (Author).

Book excerpt: Lasers with a gaseous active medium offer high flexibility, wide tunability, and advantages in cost, beam quality, and power scalability. Gas lasers have tended to become overshadowed by the recent popularity and proliferation of semiconductor lasers. As a result of this shift in focus, details on modern developments in gas lasers are difficult to find. In addition, different types of gas lasers have unique properties that are not well-described in other references. Collecting expert contributions from authorities dealing with specific types of lasers, Gas Lasers examines the fundamentals, current research, and applications of this important class of laser. It is important to understand all types of lasers, from solid-state to gaseous, before making a decision for any application. This book fills in the gaps by discussing the definition and properties of gaseous media along with its fluid dynamics, electric excitation circuits, and optical resonators. From this foundation, the discussion launches into the basic physics, characteristics, applications, and current research efforts for specific types of gas lasers: CO lasers, CO2 lasers, HF/DF lasers, excimer lasers, iodine lasers, and metal vapor lasers. The final chapter discusses miscellaneous lasers not covered in the previous chapters. Collecting hard-to-find material into a single, convenient source, Gas Lasers offers an encyclopedic survey that helps you approach new applications with a more complete inventory of laser options.
