Available in PDF, EPUB and Kindle. Book excerpt: To describe subcritical combustion, there are quasisteady theories based on the fact that the ratio of gas density to liquid density, epsilon, is small. At large pressures below critical, epsilon is not too small and unsteady effects become more important. It is found that, far from the droplet, at distances of the order of the droplet radius divided by the square root of epsilon, there is a unsteady region that originates corrections to mass burning rates, given by quasisteady theories, of order square root of epsilon. For most hydrocarbons burning in air the flame is located far from the droplet, and its position is not given, even in first approximation, by quasisteady theories. Unsteady effects are also analyzed for forced convection burning with Peclet numbers of order square root of epsilon. (Author Modified Abstract).

This book was released on 2015-03-23 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The findings of this work provides an insight into the fundamental aspects of liquid droplet combustion modelling by developing different droplet sub models. An unsteady, spherically symmetric, sub critical, single component gas phase model is developed first and tested for various ambient conditions of temperature, pressure, composition and fuels.It is further extended to include the effects of convection, droplet heating and emissions.A high pressure droplet vaporization model is evolved in view of the supercritical vaporization occuring in diesel engines and liquid rockets.Also, simple and detailed multi component droplet vaporization/combustion models are developed, since commercial fuels used in engines are multi component fuels.The discrete droplet sub models are simple and realistic requiring less computation time and therefore feasible for their implementation in spray combustion codes where CPU economy is vital.

Download or read book Dust Explosion Dynamics written by Russell A. Ogle and published by Butterworth-Heinemann. This book was released on 2016-09-10 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dust Explosion Dynamics focuses on the combustion science that governs the behavior of the three primary hazards of combustible dust: dust explosions, flash fires, and smoldering. It explores the use of fundamental principles to evaluate the magnitude of combustible dust hazards in a variety of settings. Models are developed to describe dust combustion phenomena using the principles of thermodynamics, transport phenomena, and chemical kinetics. Simple, tractable models are described first and compared with experimental data, followed by more sophisticated models to help with future challenges. Dr. Ogle introduces the reader to just enough combustion science so that they may read, interpret, and use the scientific literature published on combustible dusts. This introductory text is intended to be a practical guide to the application of combustible dust models, suitable for both students and experienced engineers. It will help you to describe the dynamics of explosions and fires involving dust and evaluate their consequences which in turn will help you prevent damage to property, injury and loss of life from combustible dust accidents. Demonstrates how the fundamental principles of combustion science can be applied to understand the ignition, propagation, and extinction of dust explosions Explores fundamental concepts through model-building and comparisons with empirical data Provides detailed examples to give a thorough insight into the hazards of combustible dust as well as an introduction to relevant scientific literature

Download or read book Combustion of Liquid Fuel Sprays written by Alan Williams and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combustion of Liquid Fuel Sprays outlines the fundamentals of the combustion of sprays in a unified way which may be applied to any technological application. The book begins with a discussion of the general nature of spray combustion, the sources of liquid fuels used in spray combustion, biomass sources of liquid fuels, and the nature and properties of fuel oils. Subsequent chapters focus on the properties of sprays, the atomization of liquid fuels, and the theoretical modeling of the behavior of a spray flame in a combustion chamber. The nature and control of pollutants from spray combustion, the formation of deposits in oil-fired systems, and the combustion of sprays in furnaces and engines are elucidated as well. The text is intended for students undertaking courses or research in fuel, combustion, and energy studies.

Available in PDF, EPUB and Kindle. Book excerpt: A study of the droplet gasification and combustion characteristics of hydrocarbon fuel droplets was conducted at sub- and supercritical. The experimental setup provided quiescent and convective environments under supercritical pressure and temperature conditions. The droplet combustion experiment hardware consisted of: a liquid pressurizing and transfer system; a high pressure and temperature combustion chamber; a droplet formation, deployment and ignition system; and a high speed CCD imaging system. The gasification and combustion characteristics of droplets of several hydrocarbons under quiescent environments were studied. Specifically, the mass emission rates and combustion characteristics of 1.5-mm-diameter suspended droplets of a series of hydrocarbons ranging from hexane (C6) to tetradecane (Cl4) were measured at sub- and supercritical pressures and temperatures using the high-speed image system. The images of droplet gasification and combustion revealed interesting phenomena and provided better understanding of the droplet behavior in sub- and supercritical pressure and temperature environments.
