Inorganic Geochemistry of Coal explains�how to determine the concentrations and modes of occurrence of elements in coal, how to diminish adverse effects of toxic elements on the environment and human health, which elements in coal could be industrially utilized, and which elements can be successfully used as indications for deciphering depositional environments and tectonic evolution. As coal use will remain at an all-time high for the next several decades, there is a critical need for understanding the properties of this fuel to ensure efficient use, encourage its economic by-product potential, and to help minimize its negative technological, environmental and health impacts. Features dozens of never-before published illustrations of critical features of the inorganic geochemistry of coal Covers both the theory and applications of the topic, including case studies to serve as real-world examples Includes a chapter on the health and environmental impacts of the mining, development and use of coal

Early Continent Evolution of the North China Craton discusses the tectono-thermal regimes of the early continental crust in the North China Craton (NCC), from the Hadean to the early Paleoproterozoic, reconstructing the evolutional framework and facilitating comprehensive understanding of the early continent evolution of the NCC. The book systematically summarizes the Neoarchean metamorphism of the NCC and discusses the implications for the tectonic models of the NCC through compiling evolutional information of the Hadean to the early Paleoproterozoic sequences in the NCC.Researchers, academics, and students in geology (especially Precambrian Geology), geomorphology, geophysics, and geological engineering will benefit from using this book in applying tectonic models to other cratonic blocks globally, and will understand evolutional information of the largest and oldest cratonic block in China.

Completely covers all key issues and research frontiers of the early continental evolution of the North China Craton (NCC), from the Hadean to the early PaleoproterozoicSystematically summarizes the Neoarchaean metamorphism of the NCC and discusses the implications for tectonic modelsIncludes discussion on controversial views on tectonic regimes of the NCC during the Archean to early Paleoproterozoic, with objective conclusions

This book concentrates on high-fidelity numerical methods for predicting internal flows within aeroengines’ compressors. A distinctive features of this work is the establishment of a comprehensive research framework. Specifically, it starts with engineering application requirements and integrates high-performance parallel algorithms to develop detached eddy simulation (DES)-series methods tailored to the needs of compressor design. Additionally, it encompasses the development of data analysis methods suitable for handling the "vast" amounts of high-fidelity unsteady flow data in compressors and the high spatial resolution experimental results. This book takes us from making the intricate details of compressor flow field structures "visible" to “explainable”. Another noteworthy aspect of this book is its practical orientation, seamlessly intergrating theoretical concepts with practical applications. Herein, it addresses three major engineering problems in detail and elucidates the technical approaches involving advanced numerical methods and data analysis techniques for solving these physical problems.The book highlights the challenging issues associated with complex internal flows in compressors, the governing equations for DES-series methods, and the implementation strategies for numerical simulations of internal compressor flows. They also delve into data-driven analysis methods for unsteady flow field data, high-fidelity numerical simulations of flow in the blade root region of compressors, dynamic flow capture methods in the tip region of compressor blades, and simulation and analysis of flow fields in inlet distortion generators.This book serves as a valuable reference for researchers and engineering professionals in the aerospace, computational fluid dynamics, and high-performance turbomachinery fields. Additionally, it can be used as a specialized textbook for doctoral and master's students in disciplines such as aerospace science and technology, power engineering, and engineering thermophysics.

The topics covered include but are not limited to: wireless power transfer technology and systems, coupling mechanism and electromagnetic field of wireless power transfer systems, latest developments in wireless power transfer system, and wide applications.
