Book Description
This monograph presents an application of the first- order conditional moment closure (CMC) approach to modelling turbulent non-premixed flames of methane, propane and ethylene, with particular attention given to sooting flames. One objective of the current research is to investigate the practicability of incorporating gas-phase chemical mechanisms of varying length and complexity into calculations of turbulent non-premixed flames. Another objective is to extend the current scope of CMC combustion modelling by incorporating calculations of detailed gas-phase chemistry, soot formation and oxidation, and radiative heat transfer. Overall, predictions are in far better accord with experimental data when differential diffusion is accounted for in the model, and realistic prediction of soot levels are not possible without the incorporation of such effects. Given the simplicity and relative accuracy of the model described, it offers potential for future development to cover a wide range of hydrocarbon fuels, including the high hydrocarbons used in practical combustors, as well as for application in complex combustor's geometries.

Book Description
This thesis describes the application of the first-order Conditional Moment Closure (CMC) to the autoignition of high-pressure fuel jets, and to piloted and lifted turbulent jet flames using classical and advanced CMC submodels. A Doubly-Conditional Moment Closure (DCMC) formulation is further proposed.

Book Description
Turbulent combustion sits at the interface of two important nonlinear, multiscale phenomena: chemistry and turbulence. Its study is extremely timely in view of the need to develop new combustion technologies in order to address challenges associated with climate change, energy source uncertainty, and air pollution. Despite the fact that modeling of turbulent combustion is a subject that has been researched for a number of years, its complexity implies that key issues are still eluding, and a theoretical description that is accurate enough to make turbulent combustion models rigorous and quantitative for industrial use is still lacking. In this book, prominent experts review most of the available approaches in modeling turbulent combustion, with particular focus on the exploding increase in computational resources that has allowed the simulation of increasingly detailed phenomena. The relevant algorithms are presented, the theoretical methods are explained, and various application examples are given. The book is intended for a relatively broad audience, including seasoned researchers and graduate students in engineering, applied mathematics and computational science, engine designers and computational fluid dynamics (CFD) practitioners, scientists at funding agencies, and anyone wishing to understand the state-of-the-art and the future directions of this scientifically challenging and practically important field.

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.
