Thermodynamics and heat Books

Book SynopsisThis textbook is the result of many years of teaching quantum and statistical mechanics, drawing on exercises and exam papers used on courses taught by the authors. The subjects of the exercises have been carefully selected to cover all the material which is most needed by students. Each exercise is carefully solved in full details, explaining the theory behind the solution with particular care for those issues that students often find difficult, or which are often neglected in other books on the subject. The exercises in this book never require extensive calculations but tend to be somewhat unusual and force the solver to think about the problem starting from first principles, rather than by analogy with some previously solved exercise.Table of ContentsIntroduction to Quantum Mechanics.- Problems on Quantum Mechanics.- Problems on Statistical Mechanics.

Book SynopsisThermal-hydraulic instability can potentially impair thermal reliability of reactor cores or other power equipment components. Thus it is important to address stability issues in power equipment associated with thermal and nuclear installations, particularly in thermal nuclear power plants, chemical and petroleum industries, space technology, and radio, electronic, and computer cooling systems. Coolant Flow Instabilities in Power Equipment synthesizes results from instability investigations around the world, presenting an analysis and generalization of the published technical literature.The authors include individual examples on flow stability in various types of equipment, including boilers, reactors, steam generators, condensers, heat exchangers, turbines, pumps, deaerators, bubblers, and pipelines. They also present information that has not been widely available until recently, such as thermal-acoustic instability, flow instability with supercritical paraTable of ContentsPhase Flow Oscillatory Thermal-Hydraulic Instability.

Book SynopsisSpace–time transformations as a design tool for a new class of composite materials (metamaterials) have proved successful recently. The concept is based on the fact that metamaterials can mimic a transformed but empty space. Light rays follow trajectories according to Fermat’s principle in this transformed electromagnetic, acoustic, or elastic space instead of laboratory space. This allows one to manipulate wave behaviors with various exotic characteristics such as (but not limited to) invisibility cloaks. This book is a collection of works by leading international experts in the fields of electromagnetics, plasmonics, elastodynamics, and diffusion waves. The experimental and theoretical contributions will revolutionize ways to control the propagation of sound, light, and other waves in macroscopic and microscopic scales. The potential applications range from underwater camouflaging and electromagnetic invisibility to enhanced biosensors and protection from harmful physical waves (e.g., tsunamis and earthquakes). This is the first book that deals with transformation physics for all kinds of waves in one volume, covering the newest results from emerging topical subjects such as transformational plasmonics and thermodynamics.Table of ContentsPart 1: Non-Classical, Non-Linear Transport. Properties of quantum transport. Non-equilibrium transport. Resonant tunneling. Longitudinal transport of superlattices. Mesoscopic transport. Transport in quantum dots. Silicon single electron transistor. Silicon single electron memory. Part 2: Quantum Waveguide Theory. Properties of quantum transport. One-dimensional quantum waveguide theory. Two-dimensional quantum waveguide theory. One-dimensional quantum waveguide theory of Rashba electron. One-dimensional quantum waveguide theory of Rashba electrons in curved circuits. Spin polarization of Rashba electron with mixed state. Two-dimensional quantum waveguide theory of Rashba electrons.
