Download or read book Vaporization Ignition and Combustion of Two Parallel Fuel Droplet Streams written by R. H. Rangel and published by . This book was released on 1987 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of the combined mechanisms of heat transfer, vaporization, ignition, and combustion of two parallel fuel droplet streams injected in a hot, oxidizing gas flow is presented. The analysis gives a qualitative understanding of the various complex phenomena involved in the vaporization and ignition of one stream of droplets followed by the propagation of the flame to a second stream and the establishment of diffusion flames surrounding each droplet stream. The two-dimensional physical model consists of a constant-property oxidizing gas flowing with a uniform velocity between two insulated planes. The temperature of the gas at the inlet of the channel is specified. The fuel droplet streams are represented as two parallel droplet sheets injected at prescribed locations within the gas flow. Liquid temperature, droplet radius, as well as droplet sheet density and velocity are specified at the inlet. Keywords: Spray combustion, Ignition of sprays, Flame propagation in sprays.

Available in PDF, EPUB and Kindle. Book excerpt: An analysis is presented of the mechanisms of heat transfer and vaporization in an idealized two-dimensional fuel spray consisting of two parallel droplet streams injected in a hot gas. With the assumption of a constant relative velocity between the gas and liquid phases (inviscid approximation), a system of partial differential equations with linear operators and non-linear source terms is obtained. With the use of Green's functions, this system is transformed into a group of non-linear ordinary differential equations and integral equations which are readily solved with numerical techniques. The dimensionless groups influencing the problem are identified and a discussion is presented of the effects of four relevant parameters including: a vaporization- diffusion time ratio, a liquid-gas mass flow ratio, a Spalding transfer number, and a Reynolds number. The method yields qualitatively correct estimates of the behavior of the gas and liquid phases which may serve as guidelines in the development of costlier numerical schemes. Keywords: Spray; Combustion; Ignition; Flames; Propagation.

Download or read book Combustion Science and Engineering written by Kalyan Annamalai and published by CRC Press. This book was released on 2006-12-19 with total page 1200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Students embarking on their studies in chemical, mechanical, aerospace, energy, and environmental engineering will face continually changing combustion problems, such as pollution control and energy efficiency, throughout their careers. Approaching these challenges requires a deep familiarity with the fundamental theory, mathematics, and physical concepts of combustion. Based on more than two decades of teaching experience, Combustion Science and Engineering lays the necessary groundwork while using an illustrative, hands-on approach. Taking a down-to-earth perspective, the book avoids heavy mathematics in the first seven chapters and in Chapter 17 (pollutants formation and destruction), but considers molecular concepts and delves into engineering details. It begins with an outline of thermodynamics; basics of thermochemistry and chemical equilibrium; descriptions of solid, liquid, and gaseous fuels; chemical kinetics and mass transfer; and applications of theory to practical systems. Beginning in chapter 8, the authors provide a detailed treatment of differential forms of conservation equations; analyses of fuel combustion including jet combustion and boundary layer problems; ignition; flame propagation; interactive and group combustion; pollutant formation and control; and turbulent combustion. In addition, this textbook includes abundant examples, illustrations, and exercises, as well as spreadsheet software in combustion available for download. This software allows students to work out the examples found in the text. Combustion Science and Engineering imparts the skills and foundational knowledge necessary for students to successfully approach and solve new problems.
