This book was released on 2017 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Two combustion systems that are extensively studied for chemical reaction processes are premixed flames and non-premixed flames. A premixed flame has oxidizer mixed with fuel causing flame front to be a thin reaction sheet (flame) that moves from burnt side to reactant side. Plenty of theoretical and physical experiments have already been contributed into modeling and characterizing premixed flames. Only as of late, has the theoretical and physical experiments towards non-premixed flames, been identified in the literature. This research focuses on non-premixed flames, diffusion flames. A diffusion flame is where oxidizer and fuel are initially separated and come together via some external forces at a reaction sheet. As a flame cools down, or slows down, the flame gets closer to extinction. Before extinction the flame will become unstable and may oscillate or show cellular instabilities. This model will focus on diffusion flames in a closed chamber with fuel being supplied in the flow and oxidizer diffusing against the gradient. The model allows for convection and radiative heat loss, which represents the heat transfer of a hot object to its cooler surroundings. Appropriate boundary conditions are implemented for the three differential equations that include temperature, oxidizer, and fuel. The system of equations are coupled, and each has a nonlinear reaction term. The bvp4c function in MATLAB is used to numerically solve these differential equations, with their boundary conditions, to identify flame location and flame extinctions for diffusion flames. Flame extinction occurs at a particular Damköhler number D, representing the ratio of diffusion time to chemical reaction time. Results from the numerical analysis are compared to numerical results of other models that are similar to this model."--

Book Synopsis Effects of Gas-phase Radiation and Detailed Kinetics on the Burning and Extinction of a Solid Fuel by : Jennifer L. Rhatigan
Download or read book Effects of Gas-phase Radiation and Detailed Kinetics on the Burning and Extinction of a Solid Fuel written by Jennifer L. Rhatigan and published by . This book was released on 2001 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first attempt to analyze both radiation and detailed kinetics on the burning and extinction of a solid fuel in a stagnation-point diffusion flame. We present a detailed and comparatively accurate computational model of a solid fuel flame along with a quantitative study of the kinetics mechanism, radiation interactions, and the extinction limits of the flame. A detailed kinetics model for the burning of solid trioxane (a trimer of formaldehyde) is coupled with a narrowband radiation model, with carbon dioxide, carbon monoxide, and water vapor as the gas-phase participating media. The solution of the solid trioxane diffusion flame over the flammable regime is presented in some detail, as this is the first solution of a heterogeneous trioxane flame. We identify high-temperature and low-temperature reaction paths for the heterogeneous trioxane flame. We then compare the adiabatic solution to solutions that include surface radiation only and gas-phase and surface radiation using surface model.
Book Synopsis Combustion Theory by : Forman A. Williams
Download or read book Combustion Theory written by Forman A. Williams and published by CRC Press. This book was released on 2018-03-05 with total page 705 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combustion Theory delves deeper into the science of combustion than most other texts and gives insight into combustions from a molecular and a continuum point of view. The book presents derivations of the basic equations of combustion theory and contains appendices on the background of subjects of thermodynamics, chemical kinetics, fluid dynamics, and transport processes. Diffusion flames, reactions in flows with negligible transport and the theory of pre-mixed flames are treated, as are detonation phenomena, the combustion of solid propellents, and ignition, extinction, and flamibility pehnomena.

Book Synopsis Reduced Kinetic Mechanisms for Applications in Combustion Systems by : Norbert Peters
Download or read book Reduced Kinetic Mechanisms for Applications in Combustion Systems written by Norbert Peters and published by Springer Science & Business Media. This book was released on 2008-09-11 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: In general, combustion is a spatially three-dimensional, highly complex physi co-chemical process oftransient nature. Models are therefore needed that sim to such a degree that it becomes amenable plify a given combustion problem to theoretical or numerical analysis but that are not so restrictive as to distort the underlying physics or chemistry. In particular, in view of worldwide efforts to conserve energy and to control pollutant formation, models of combustion chemistry are needed that are sufficiently accurate to allow confident predic tions of flame structures. Reduced kinetic mechanisms, which are the topic of the present book, represent such combustion-chemistry models. Historically combustion chemistry was first described as a global one-step reaction in which fuel and oxidizer react to form a single product. Even when detailed mechanisms ofelementary reactions became available, empirical one step kinetic approximations were needed in order to make problems amenable to theoretical analysis. This situation began to change inthe early 1970s when computing facilities became more powerful and more widely available, thereby facilitating numerical analysis of relatively simple combustion problems, typi cally steady one-dimensional flames, with moderately detailed mechanisms of elementary reactions. However, even on the fastest and most powerful com puters available today, numerical simulations of, say, laminar, steady, three dimensional reacting flows with reasonably detailed and hence realistic ki netic mechanisms of elementary reactions are not possible.
