Book Description
Numerical studies were performed to examine different strut configurations to determine their mixing characteristics for possibly use with fuel-injector ports for round scram jet-combustor applications. Several strut configurations were tested to provide a better understanding of the flow physics, in terms of pressure, total pressure recovery, vorticity magnitude, streamlines, and velocity vectors. The conceptual strut designs were placed in a rectangular flow path, and the computations will be followed by an experimental program in the AFRL/RZA Research Cell 19 supersonic wind-tunnel facility, which has a rectangular cross-section area of 12.7 cm x 15.24 cm. The struts were sized, however, for eventual use in a 25.4 cm (10-inch) round combustor. The strut with a constant leading-edge angle and a moderately swept trailing edge seems to provide reasonably good mixing flow features without significantly compromising the total pressure recovery.

Book Description
Sonochemistry is studied primarily by chemists and sonoluminescence mainly by physicists, but a single physical phenomenon - acoustic cavitation - unites the two areas. The physics of cavitation bubble collapse, is relatively well understood by acoustical physicists but remains practically unknown to the chemists. By contrast, the chemistry that gives rise to electromagnetic emissions and the acceleration of chemical reactions is familiar to chemists, but practically unknown to acoustical physicists. It is just this knowledge gap that the present volume addresses. The first section of the book addresses the fundamentals of cavitation, leading to a more extensive discussion of the fundamentals of cavitation bubble dynamics in section two. A section on single bubble sonoluminescence follows. The two following sections address the new scientific discipline of sonochemistry, and the volume concludes with a section giving detailed descriptions of the applications of sonochemistry. The mixture of tutorial lectures and detailed research articles means that the book can serve as an introduction as well as a comprehensive and detailed review of these two interesting and topical subjects.

Book Description
This book will provide the necessary theoretical background and a description of plasma-related devices and processes that are used industrially for physicists and engineers. It is a self-contained introduction to the principles of plasma engineering with comprehensive references. This volume also includes the terminology, jargon and acronyms used in the field of industrial plasma engineering - indexed when they first appear in the text - along with their definitions and a discussion of their meaning. It is aimed at assisting the student in learning key terminology and concepts, and providing the in-service engineer or scientist with a technical glossary. An extensive index and appendices enhance the value of this book as a key reference source. These incorporate a list of the nomenclature used in mathematical expressions in the text, physical constants, and often-used plasma formulae. SI units are used throughout. Intended for students from all engineering and physical science disciplines, and as a reference source by in-service engineers. Coverage: * basic information on plasma physics and the physical processes important in industrial plasmas * sources of ion and electron beams and ionizing radiation used in industrial applications * physics and technology of DC and RF electrical discharges.
