Book Description
Non-premixed combustion process is an important subject in most applications of combustion. Understanding of this phenomenon is crucial in the design of reliable, efficient, economical power generation systems. Microfabrication technologies in the development of power micro electro-mechanical systems is also becoming an increasing trend nowadays and the complete understanding of microfluid dynamics and non-premixed micro-combustion phenomena will lead the success in this field. In recent years numerical simulations have become an essential tool to understand combustion process to overcome experimental problems without losing accuracy. In this study, two numerical simulations were performed on the analysis of the effect of injection on the turbulent mixing quality in a simple combustor and on the dynamics non-premixed flame street in a mesoscale channel using the commercial software Fluent®. The effect of inlet geometries were first investigated for a Lockwood-type combustor in terms of combustion and energy efficiency and an efficient design configuration is deduced. The effect of wall temperature and flow velocities on the dynamics of non-premixed flame in a scaled combustion channel was investigated in the second part of this study. The results suggest that the two main parameters affecting the development of a non-premixed flame street in a mesoscale channel are the heat transfer to and from the wall and the diffusion time of the flow. The analysis of numerical details such as grid resolution, turbulent and chemistry models is emphasized throughout the study to understand the influence of these numerical parameters on the simulated phenomenon by comparing with experimental observations.

Book Description
This book presents a comprehensive review of state-of-the-art models for turbulent combustion, with special emphasis on the theory, development and applications of combustion models in practical combustion systems. It simplifies the complex multi-scale and nonlinear interaction between chemistry and turbulence to allow a broader audience to understand the modeling and numerical simulations of turbulent combustion, which remains at the forefront of research due to its industrial relevance. Further, the book provides a holistic view by covering a diverse range of basic and advanced topics—from the fundamentals of turbulence–chemistry interactions, role of high-performance computing in combustion simulations, and optimization and reduction techniques for chemical kinetics, to state-of-the-art modeling strategies for turbulent premixed and nonpremixed combustion and their applications in engineering contexts.

Turbulent Premixed Flames

Pages : 447
Book Description
A work on turbulent premixed combustion is important because of increased concern about the environmental impact of combustion and the search for new combustion concepts and technologies. An improved understanding of lean fuel turbulent premixed flames must play a central role in the fundamental science of these new concepts. Lean premixed flames have the potential to offer ultra-low emission levels, but they are notoriously susceptible to combustion oscillations. Thus, sophisticated control measures are inevitably required. The editors' intent is to set out the modeling aspects in the field of turbulent premixed combustion. Good progress has been made on this topic, and this cohesive volume contains contributions from international experts on various subtopics of the lean premixed flame problem.
