This book was released on 1967 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: In solving the problem of flame stabilization, it is necessary to consider equally both the flow structure behind the bluff bodies and the kinetics of the chemical reaction. The article demonstrates, however, that, with certain assumptions and simplifications, the blow-out characteristics of a flame holder in the form of a bluff body can be satisfactorily explained and calculated, by using the thermal theory of ignition and the theory of turbulent flow. In deriving quantitative correlations, the following assumptions were made: (1) Up to the ignition point, the velocity, temperature, and concentration distributions of the turbulent boundary layer behind the holder are in accordance with the theory of turbulent flows for nonisothermal counter flows; they are not changed by the heat release resulting from the chemical reaction, for, according to the thermal theory of ignition, during the period of ignition delay, the heat release and temperature rise are insignificant. (2) The static pressure in the boundary layer behind the holder is equal to the free-stream static pressure. An expression was derived to determine the effect on the blow-out characteristics of the combustion chamber of the physical flow parameters (pressure, flow velocity, temperature) and type of fuel. If the dependence of the length of the reverse-flow zone on the dimension and shape of flame holder are known, the effect of its geometric parameters may also be determined. (Author).

Download or read book Unsteady Combustor Physics written by Tim C. Lieuwen and published by Cambridge University Press. This book was released on 2012-08-27 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing clean, sustainable energy systems is a pre-eminent issue of our time. Most projections indicate that combustion-based energy conversion systems will continue to be the predominant approach for the majority of our energy usage. Unsteady combustor issues present the key challenge associated with the development of clean, high-efficiency combustion systems such as those used for power generation, heating or propulsion applications. This comprehensive study is unique, treating the subject in a systematic manner. Although this book focuses on unsteady combusting flows, it places particular emphasis on the system dynamics that occur at the intersection of the combustion, fluid mechanics and acoustic disciplines. Individuals with a background in fluid mechanics and combustion will find this book to be an incomparable study that synthesises these fields into a coherent understanding of the intrinsically unsteady processes in combustors.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a step-by-step methodology for the design of ramjet engines. It explores ramjet combustion, provides guidelines on how to size the engines, and discusses performance analysis. The book begins with an introduction to ramjet design, including fundamental definitions in the field. It then discusses ramjet engine performance, and fuels which can be used. Several types of ramjet engines are then explored, and guidelines for their design are presented, including flame holders, injectors, and combustors. Finally, the book concludes with a discussion of the types of materials which should be used for ramjet engines. This book is of interest to engine designers and engineers, researchers, and graduate students, as it collates research in a succinct, clear guide to the issue of designing ramjet engines.
