Book Description
This volume contains reviewed papers. The invited lectures considered the many challenges posed by adding one element to the base formed by others: turbulence and turbulent mixing in the absence of combustion through to turbulent mixing dominated by chemistry and combustion. The Symposium benefited from experimental, theoretical and computational contributions, which were focussed on either fundamental or more practical questions. Extensive discussions that followed each paper are included and add to the richness of the Proceedings.

Book Description
L'OBJET DE CETTE THESE CONCERNE LA MODELISATION DES ECOULEMENTS REACTIFS TURBULENTS. L'OBJECTIF VISE CONSISTE A DEVELOPPER UN MODELE SUSCEPTIBLE DE PREDIRE LA FORMATION DES POLLUANTS COMME LE MONOXYDE D'AZOTE NO OU LE MONOXYDE DE CARBONE CO DANS DES FOYERS TRIDIMENSIONNELS COMPLEXES. POUR Y PARVENIR, ON FAIT APPEL A UNE APPROCHE PROBABILISTE EULERIENNE LAGRANGIENNE (PEUL) OU LE CHAMP DE VITESSE EST CALCULE A L'AIDE DES EQUATIONS EULERIENNES DE BILAN MOYENNEES ET LE CHAMP DE COMPOSITION ET DE TEMPERATURE PAR UNE METHODE DITE A TRANSPORT DE PDF (PROBABILITY DENSITY FUNCTION) LAGRANGIENNE. LA MODELISATION DES TERMES INCONNUS DE DISPERSION TURBULENTE ET DE MELANGE AUX PETITES ECHELLES EST DETAILLEE. DES MECANISMES REDUITS ET UN MECANISME DETAILLE D'OXYDATION DU COMBUSTIBLE (QUI EST ICI LE METHANE, CH4) AINSI QUE LE MECANISME DE FORMATION DU NO THERMIQUE SONT INTRODUITS ET TESTES. ON PRESENTE LES RESULTATS OBTENUS AVEC LE MODELE PEUL DANS TROIS CONFIGURATIONS EXPERIMENTALES. LES COMPARAISONS CALCUL-EXPERIENCE DEMONTRENT LA CAPACITE DU MODELE A PREDIRE LA FORMATION DU NO THERMIQUE ET (PARTIELLEMENT) DU PROMPT NO, DU CO DANS DES CONFIGURATIONS BI ET TRIDIMENSIONNELLES AINSI QU'A REPRESENTER CORRECTEMENT UN REGIME D'EXTINCTION LOCALE DE LA FLAMME.

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.

Book Description
This book presents methodologies for analysing large data sets produced by the direct numerical simulation (DNS) of turbulence and combustion. It describes the development of models that can be used to analyse large eddy simulations, and highlights both the most common techniques and newly emerging ones. The chapters, written by internationally respected experts, invite readers to consider DNS of turbulence and combustion from a formal, data-driven standpoint, rather than one led by experience and intuition. This perspective allows readers to recognise the shortcomings of existing models, with the ultimate goal of quantifying and reducing model-based uncertainty. In addition, recent advances in machine learning and statistical inferences offer new insights on the interpretation of DNS data. The book will especially benefit graduate-level students and researchers in mechanical and aerospace engineering, e.g. those with an interest in general fluid mechanics, applied mathematics, and the environmental and atmospheric sciences.

Book Description
Numerical Modeling of Turbulent Combustion provides readers with a comprehensive understanding of the specificities involved in numerical simulation of gaseous turbulent reactive flows and flames, including their most current applications. This title is intended for individuals with a background in fluid mechanics who are seeking to delve into the fundamentals of turbulent combustion modeling. It offers methodologies to simulate flames while taking into account their multi-physics character. Moreover, the text addresses emerging numerical technologies within this field and highlights the relevance of new sustainable fuels. The structure of the book is carefully organised to cover various aspects. It begins with an exploration of the fundamentals of aerothermochemistry, presenting key quantities and their corresponding balance equations that require numerical solutions. The book then delves into the essential concepts and tools necessary to handle the strongly non-linear nature of turbulent flames, with a specific focus on the interplay between turbulence and chemistry. Furthermore, readers will gain insights into the numerical modeling of flames within the context of sustainable combustion. This includes the introduction of novel fuels, such as hydrogen and solid metals, which have become increasingly relevant in recent times. The book also takes into account cutting-edge techniques, like the systematic integration of machine learning in numerical simulations of complex systems and the lattice Boltzmann approach. These innovations open new possibilities for tackling challenges in numerical turbulent combustion research. Both the fundamental methods and modeling tools are presented in detail, along with best practice guidelines for their practical application in simulations. This ensures that readers not only grasp the underlying theories but also gain valuable insights into how to implement these techniques effectively. Overall, Numerical Turbulent Combustion serves as a valuable resource for researchers and practitioners alike, offering a comprehensive and up-to-date understanding of numerical simulations in the field of turbulent combustion.
