This book was released on 2018-06-24 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sequential two-stage, natural gas fueled power generation combustion system is modeled to examine the fundamental aerodynamic and combustion characteristics of the system. The modeling methodology includes CAD-based geometry definition, and combustion computational fluid dynamics analysis. Graphical analysis is used to examine the complex vortical patterns in each component, identifying sources of pressure loss. The simulations demonstrate the importance of including the rotating high-pressure turbine blades in the computation, as this results in direct computation of combustion within the first turbine stage, and accurate simulation of the flow in the second combustion stage. The direct computation of hot-streaks through the rotating high-pressure turbine stage leads to improved understanding of the aerodynamic relationships between the primary and secondary combustors and the turbomachinery.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: Exposes a Powerful Material-Making Tool Dedicated to the physical, chemical, and structural transformations that take place during combustion synthesis (CS) of advanced materials, Combustion for Material Synthesis analyzes the nature of solid flame phenomenon and provides readers with undisputed proof that ‘fire’ is a powerful tool used in making materials. Of interest to specialists in the field of materials engineering, this book explores the physical and chemical principles of synthesis of materials in the self-sustained combustion mode. It describes mechanisms for a variety of solid–solid and gas–solid reactions and examines structure and properties of different materials produced by CS. The authors discuss a wide range of topics, including phenomenology, theory, experimental methods and observations, as well as properties of the product synthesized and approaches for large-scale materials production using the combustion synthesis technique. They examine conventional concepts and present recent breakthroughs in the field of materials synthesis by rapid self-sustained reactions that include fabrication of different nanomaterials. They compare CS with other methods, factoring in different types of combustion processes, including processes that can occur in a vacuum, inert gas, or oxygen-free atmosphere. Covering research on topics that have been around for a while, but not widely circulated, this work: Outlines in detail both fundamental aspects of CS, including modern theoretical approaches and advanced in situ experimental methods Examines the advantages and disadvantages, achievements, and challenges remained in heterogeneous combustion used for material synthesis Explores the emergence of a new fundamental direction in material science, i.e., structural macrokinetics Details new technologies that are based on fundamental scientific discoveries and innovative scientific ideas Analyzes structure and properties of variety of CS materials, including nanomaterials Authored by world-recognized specialists in the field of combustion synthesis for advanced materials, Combustion for Material Synthesis presents the state of the art in R&D in the field of CS, focusing on the fabrication of novel materials. It is intended for researchers, engineers, and graduate students from different disciplines and is also suggested as recommended reading for materials science courses.

This book was released on 2021-08-18 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofuels have recently attracted a lot of attention, mainly as alternative fuels for applications in energy generation and transportation. The utilization of biofuels in such controlled combustion processes has the great advantage of not depleting the limited resources of fossil fuels while leading to emissions of greenhouse gases and smoke particles similar to those of fossil fuels. On the other hand, a vast amount of biofuels are subjected to combustion in small-scale processes, such as for heating and cooking in residential dwellings, as well as in agricultural operations, such as crop residue removal and land clearing. In addition, large amounts of biomass are consumed annually during forest and savanna fires in many parts of the world. These types of burning processes are typically uncontrolled and unregulated. Consequently, the emissions from these processes may be larger compared to industrial-type operations. Aside from direct effects on human health, especially due to a sizeable fraction of the smoke emissions remaining inside residential homes, the smoke particles and gases released from uncontrolled biofuel combustion impose significant effects on the regional and global climate. Estimates have shown the majority of carbonaceous airborne particulate matter to be derived from the combustion of biofuels and biomass. “Production of Biofuels and Numerical Modelling of Chemical Combustion Systems” comprehensively overviews and includes in-depth technical research papers addressing recent progress in biofuel production and combustion processes. To be specific, this book contains sixteen high-quality studies (fifteen research papers and one review paper) addressing techniques and methods for bioenergy and biofuel production as well as challenges in the broad area of process modelling and control in combustion processes.
