Flow, Mixing and Heat Transfer in Furnaces


Book Description

HMT: The Science & Application of Heat and Mass Transfer: Reports, Reviews & Computer Programs, Volume 2: Flow, Mixing and Heat Transfer in Furnaces is a collection of papers from the First Conference on Mechanical Power Engineering. The title presents experimental and theoretical research in the field of flow, mixing, and heat transfer in furnaces. The experimental papers in the selection include the effect of the exit section geometry and furnace length on mixing in a cold model industrial furnace, as well as the effect of some parameters on the characteristics of heat liberated along a cylindrical reversed flow furnace. The theoretical papers tackle topics such as study of mixing of two coaxial swirling jets in a cold model furnace and numerical computations of turbulent swirling flames in axisymmetric combustors. The book will be of great use to students, researchers, and practitioners of mechanical engineering.




Review of Furnace Modeling


Book Description

There has been a spurt of recent activity in developing and applying numerical modeling to combustors and furnaces. The purpose of this review is to provide a brief overview of these recent developments and draw conclusions on the scope for further work in the area of modeling. A brief qualitative review of the various models that have been developed is presented. The models show a progressive recognition of the complexity of turbulence-chemistry interactions and attempts to include more recent submodels of such interactions. There are attempts to incorporate the three-dimensional character of fluid flows and solve the elliptic equations arising in recirculating flows. Flux models of radiation transfer are being included in the energy transport equations. Efficient numerical algorithms are being developd to solve the finite difference form of a set of elliptic, partial differential equations. The test of the success of modeling lies, obviously, in comparison with experimental measurements. Such experiments are being undertaken, but, the techniques of measurements also need development before detailed comparison can be made. The measurements made seem to indicate qualitative agreement of model predictions with limited laboratory measurements. It is concluded from the review that there is still need for development in several areas including turbulence (and turbulence-chemistry interactions) modeling, liquid and solid fuel introduction, interaction with the flow and combustion, models for soot formation, and experimental validation.

Computational Fluid Dynamics in Industrial Combustion


Book Description

Although many books have been written on computational fluid dynamics (CFD) and many written on combustion, most contain very limited coverage of the combination of CFD and industrial combustion. Furthermore, most of these books are written at an advanced academic level, emphasize theory over practice, and provide little help to engineers who need to use CFD for combustion modeling. Computational Fluid Dynamics in Industrial Combustion fills this gap in the literature. Focusing on topics of interest to the practicing engineer, it codifies the many relevant books, papers, and reports written on this combined subject into a single, coherent reference. It looks at each topic from a somewhat narrow perspective to see how that topic affects modeling in industrial combustion. The editor and his team of expert authors address these topics within three main sections: Modeling Techniques-The basics of CFD modeling in combustion Industrial Applications-Specific applications of CFD in the steel, aluminum, glass, gas turbine, and petrochemical industries Advanced Techniques-Subjects rarely addressed in other texts, including design optimization, simulation, and visualization Rapid increases in computing power and significant advances in commercial CFD codes have led to a tremendous increase in the application of CFD to industrial combustion. Thorough and clearly representing the techniques and issues confronted in industry, Computational Fluid Dynamics in Industrial Combustion will help bring you quickly up to date on current methods and gain the ability to set up and solve the various types of problems you will encounter.













Modeling of Combustion Systems


Book Description

Increasing competitive pressure for improved quality and efficiency on one hand and tightening emissions and operating requirements on the other leave the modern process engineer squeezed in the middle. While effective modeling can help balance these demands, the current literature offers overly theoretical treatments on modeling that do not transl
