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."--

This book was released on 1985 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: A numerical investigation is made of the near-ignition and near-extinction characteristics of chambered diffusion flames for arbitrary Lewis numbers. In particular, for an S-shaped response curve, both dynamic ignition and extinction are found to occur at the turning points. While the stability of premixed flames has received considerable attention in the mathematical theory of laminar flames that has been developed in the last decade or so, diffusion flames have almost been ignored. Even in the context of plane flames subjected to one-dimensional disturbances there is much to be done, in particular when the response curve of steady states is S-shaped.

Available in PDF, EPUB and Kindle. Book excerpt: This introduction reviews why combustion and radiation are important, as well as the technical challenges posed by radiation. Emphasis is on interactions among turbulence, chemistry and radiation (turbulence-chemistry-radiation interactions – TCRI) in Reynolds-averaged and large-eddy simulations. Subsequent chapters cover: chemically reacting turbulent flows; radiation properties, Reynolds transport equation (RTE) solution methods, and TCRI; radiation effects in laminar flames; TCRI in turbulent flames; and high-pressure combustion systems. This Brief presents integrated approach that includes radiation at the outset, rather than as an afterthought. It stands as the most recent developments in physical modeling, numerical algorithms, and applications collected in one monograph.
