Available in PDF, EPUB and Kindle. Book excerpt: Aerospace Applications of Weakly Ionized Plasmas: * Power generation using MHD * Use of power to control aerodynamics and propulsion: (1) Surface plasmas for separation and turbulent transition control (virtual shapes) (2) Virtual shapes created by off-body energy addition for drag reduction, steering, shock control, flow turning (3) Plasma-assisted combustion. * Power extraction from one region and its use in another region (MHD bypass) * Dual-use MHD devices (both power generation and flow control): (1) Forces created by magnetic and electric fields acting on charged particles (transferred to neutral gas by collisions) (2) Ionization level per se is not critical if plasmas are used as a means of delivering energy to the flow (3) Ionization is critical in MHD power generation and flow control, and in cold-plasma generation of radicals (4) At high T (reentry, scramjet combustor) -- thermal ionization with alkali seed (5) At low T, artificial ionization is needed, and the ionization cost determines design and performance (6) Similar to ionization, cold plasma generation of chemically active species for combustion can have considerable energy cost (7) Both energy addition and extraction result in flow heating and losses of total pressure and (if in propulsion flowpath) thrust.

This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Program involving modeling and experiment to explore the utility of plasmas and magnetohydrodynamics (MHD) for aerodynamic applications. Anomalous behavior of shocks on weakly ionized plasmas has been explained in terms of conventional gas dynamics with temperature gradients. Theoretical and computational models have been developed for plasma aerodynamics and nonequilibrium MHD. Models include a new theory of nonequilibrium dissociation and vibrational relaxation and kinetics of plasmas generated by electron beams and high-voltage nanosecond pulses. Aerodynamic steering using plasma energy addition has been explored using the newly developed microwave-driven supersonic plasma wind tunnel. Potential performance of hypersonic MHD devices with electron beam ionization has been outlined. Plasma and MHD control of hypersonic flows and scramjet inlets was studied. On-ramp MHD device with ionization by electron beams was shown to be capable of maintaining the shock-on-lip condition at Mach numbers higher than the design one, while generating net power. For mass capture increase at Mach numbers lower than the design one, a new concept of.

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.
