Fundamentals Of Heat Engines

Summarizes the analysis and design of today’s gas heat engine cycles This book offers readers comprehensive coverage of heat engine cycles. From ideal (theoretical) cycles to practical cycles and real cycles, it gradually increases in degree of complexity so that newcomers can learn and advance at a logical pace, and so instructors can tailor their courses toward each class level. To facilitate the transition from one type of cycle to another, it offers readers additional material covering fundamental engineering science principles in mechanics, fluid mechanics, thermodynamics, and thermochemistry. Fundamentals of Heat Engines: Reciprocating and Gas Turbine Internal-Combustion Engines begins with a review of some fundamental principles of engineering science, before covering a wide range of topics on thermochemistry. It next discusses theoretical aspects of the reciprocating piston engine, starting with simple air-standard cycles, followed by theoretical cycles of forced induction engines, and ending with more realistic cycles that can be used to predict engine performance as a first approximation. Lastly, the book looks at gas turbines and covers cycles with gradually increasing complexity to end with realistic engine design-point and off-design calculations methods. Covers two main heat engines in one single reference Teaches heat engine fundamentals as well as advanced topics Includes comprehensive thermodynamic and thermochemistry data Offers customizable content to suit beginner or advanced undergraduate courses and entry-level postgraduate studies in automotive, mechanical, and aerospace degrees Provides representative problems at the end of most chapters, along with a detailed example of piston-engine design-point calculations Features case studies of design-point calculations of gas turbine engines in two chapters Fundamentals of Heat Engines can be adopted for mechanical, aerospace, and automotive engineering courses at different levels and will also benefit engineering professionals in those fields and beyond.

This book results from a Special Issue related to the latest progress in the thermodynamics of machines systems and processes since the premonitory work of Carnot. Carnot invented his famous cycle and generalized the efficiency concept for thermo-mechanical engines. Since that time, research progressed from the equilibrium approach to the irreversible situation that represents the general case. This book illustrates the present state-of-the-art advances after one or two centuries of consideration regarding applications and fundamental aspects. The research is moving fast in the direction of economic and environmental aspects. This will probably continue during the coming years. This book mainly highlights the recent focus on the maximum power of engines, as well as the corresponding first law efficiency upper bounds.

Professor Sandfort's history of the invention and perfection of the steam engine and the early theoretical research of Carnot, Joule, Clausius, Thompson and others is an often amusing and always fascinating story. But the main purpose of his book is to give the reader at least an elementary understanding of the first and second laws of thermodynamics, the significance of temperature, and the principle of the reversible heat engine--the theoretical foundations upon which our technological age has grown.

Salinity Gradient Heat Engines classifies all the existing SGHEs and presents an in-depth analysis of their fundamentals, applications and perspectives. The main SGHEs analyzed in this publication are Osmotic, the Reverse Electrodialysis, and the Accumulator Mixing Heat Engines. The production and regeneration unit of both cycles are described and analyzed alongside the related economic and environmental aspects. This approach provides the reader with very thorough knowledge on how these technologies can be developed and implemented as a low-impact power generation technique, wherever low-temperature waste-heat is available. This book will also be a very beneficial resource for academic researchers and graduate students across various disciplines, including energy engineering, chemical engineering, chemistry, physics, electrical and mechanical engineering. Focuses on advanced, yet practical, recovery of waste heat via salinity gradient heat engines Outlines the existing salinity gradient heat engines and discusses fundamentals, potential and perspectives of each of them Includes economics and environmental aspects Provides an innovative reference for all industrial sectors involving processes where low-temperature waste-heat is available.

An internal combustion engine (IC engine) refers to a type of heat engine wherein the combustion of fuel occurs with the help of an oxidizer in the combustion chamber, which is a significant part of the working fluid circuit. The expansion of the high-pressure and high-temperature gases generated through combustion puts direct force on certain components of an IC engine. Usually, the force is applied to turbine blades, pistons, a nozzle, or a rotor. The component is moved across a distance by this force, which converts chemical energy into kinetic energy, which is further utilized to propel, power or move whatsoever the engine is coupled with. This book is compiled in such a manner, that it will provide an in-depth knowledge about the theory and working of the internal combustion engine. The various advancements in these engines are glanced at and their applications as well as ramifications are looked at in detail. Those in search of information to further their knowledge will be greatly assisted by this book.

A concise treatment of the fundamentals of thermodynamics is presented in this book. In particular, emphasis is placed on discussions of the second law, a unique feature of thermodynamics, which states the limitations of converting thermal energy into mechanical energy. The entropy function that permits the loss in the potential of a real thermodynamic process to be assessed, the maximum possible work in a process, and irreversibility and equilibrium are deduced from the law through physical and intuitive considerations. They are applicable in mitigating waste heat and are useful for solving energy, power, propulsion and climate-related issues. The treatment is not restricted to properties and functions of ideal gases. The ideal gas assumption is invoked as a limiting case. Reversible paths between equilibrium states are obtained using reversible heat engines and reversible heat pumps between environment and systems to determine the entropy changes and the maximum work. The conditions of thermodynamic equilibrium comprising mechanical, thermal, chemical and phase equilibrium are addressed and the species formed at equilibrium in a chemical reaction at a given temperature and pressure are obtained. The molecular basis for the laws of thermodynamics, temperature, internal energy changes, entropy, reversibility and equilibrium are briefly discussed. The book serves as a reference for undergraduate and graduate students alongside thermodynamics textbooks.
