Book Description
The Ringbom engine, an elegant simplification of the Stirling, is increasingly emerging as a viable, multipurpose engine. Despite its technical elegance, high-speed stable operation capabilities, and potential as an environment-friendly energy source, the advantages manifest in Ringbom design have been slowly realized, due in large to part to its often enigmatic operating regime. This book presents for the first time a clear, tractable mathematical model of the dynamic properties of the Ringbom, resulting in a theorem that offers a complete characterization of the stable operating mode of the engine. The author here details the research leading to the development of the Ringbom and illustrates theoretical results, engine characteristics, and design principles using data from actual Ringbom engines. Throughout the book, the author emphasizes an understanding of Ringbom engine properties through closed form mathematical analysis and lucidly details how his mathematical derivations apply to real engines. Extensive descriptions of the engine hardware are included to aid those interested in their construction. Mechanical, electrical, and chemical engineers concerned with power systems, power generation, energy conservation, solar energy, and low-temperature physics will find this monograph a comprehensive and technically rich introduction to Stirling Ringbom engine technology.

Book Description
DEFINITION AND NOMENCLATURE A Stirling engine is a mechanical device which operates on a closed regenerative thermodynamic cycle with cyclic compression and expansion of the working fluid at different temperature levels. The flow of working fluid is controlled only by the internal volume changes, there are no valves and, overall, there is a net conversion of heat to work or vice-versa. This generalized definition embraces a large family of machines with different functions; characteristics and configurations. It includes both rotary and reciprocating systems utilizing mechanisms of varying complexity. It covers machines capable of operating as a prime mover or power system converting heat supplied at high tempera ture to output work and waste heat at a lower temperature. It also covers work-consuming machines used as refrigerating systems and heat pumps abstracting heat from a low temperature source and delivering this plus the heat equivalent of the work consumed to a higher tem perature. Finally it covers work-consuming devices used as pressure generators compressing a fluid from a low pressure to a higher pres sure. Very similar machines exist which operate on an open regen erative cycle where the flow of working fluid is controlled by valves. For convenience these may be called Ericsson engines but unfortunate ly the distinction is not widely established and regenerative machines of both types are frequently called 'Stirling engines'.

Book Description
This book provides invaluable and detailed information on building and optimizing Stirling engines. It's clear organization and the clarity of explanations and instructions have made the original Italian language version of this book a huge success with Stirling Engine enthusiasts. All 260 pages are printed entirely in color and contain a large number of photos and illustrations. 18 of the authors' miniature engines are presented, each with a technical description, geometric characteristics and performance data, photos, and engine technical data sheets. "Excel" files for the necessary calculations can be obtained free of charge by sending an e-mail to the author. These were created by the author for each type of engines, namely Stirling Alpha, Beta, range engines, Ringbom (vertical and horizontal cylinder) and Manson. These make it easy to both design an engine and optimize it; these calculations include all engine volumes, both functional and "dead". The text is organized so it can be understood by readers with varying degrees of knowledge: to facilitate reading, we have grouped the mathematical notes that are not essential for initial understanding at the end of the relevant chapters. The basic thermodynamic concepts are explained in these notes. The text concerns two engines types: the Stirling (including the Ringbom model, which is the best known), and the Manson, sometimes called the Ruppel engine. There are similarities between the two theoretical cycles used in each; in one respect, however, they differ considerably: the cycle used in a Stirling engine produces mechanical energy by utilizing a gas that is hermetically sealed inside; in fact, the seal is not perfect: some inevitable minor losses occur. In contrast, the Manson is not a closed cycle. The engine that uses the Stirling cycle can be made in three configurations, generally called Alfa, Beta, Gamma, in addition to a fourth, the Ringbom type, in which the displacer is "free", i.e. not connected to the crank mechanism. An important consideration for the Beta and Gamma types is the optimization of output power by establishing the correct ratio between the volume of the displacer and the volume of the working cylinder, factoring different temperatures. Efficiency is calculated and examined. The book begins with the Gamma type, which is the easiest to understand, then the remaining Alfa, Beta and Ringbom types, the latter a "free-piston" engine, and concludes with the Manson type.

Book Description
We are hearing a LOT about renewable energy these days! But unlike most available resources on alternative energy that focus on politics and economic impacts, da Rosa's practical guide, Fundamentals of Renewable Energy Processes, is dedicated to explaining the scientific and technological principles and processes that enable energy production from safe, renewable, clean sources. Advances in the renewable energy sphere are proceeding with an unprecedented speed, and in order for the world's alarming energy challenges to be solved, solid, up-to-date resources addressing the technical aspects of renewables are essential. This new, updated 2e of da Rosa's successful book continues to give readers all the background they need to gain a thorough understanding of the most popular types of renewable energy—hydrogen, solar power, biomass, wind power, and hydropower—from the ground up. The latest advances in all these technologies are given particular attention, and are carefully contextualized to help professionals and students grasp the "whys and hows" behind these breakthroughs. - Discusses how and why the most popular renewable energy sources work, including wind, solar, bio and hydrogen - Provides a thorough technical grounding for all professionals and students investigating renewable energy - The new 2e of a highly regarded guide written by an internationally renowned pioneer

Book Description
This book presents a wide-ranging review of the latest research and development directions in thermal systems optimization using population-based metaheuristic methods. It helps readers to identify the best methods for their own systems, providing details of mathematical models and algorithms suitable for implementation. To reduce mathematical complexity, the authors focus on optimization of individual components rather than taking on systems as a whole. They employ numerous case studies: heat exchangers; cooling towers; power generators; refrigeration systems; and others. The importance of these subsystems to real-world situations from internal combustion to air-conditioning is made clear. The thermal systems under discussion are analysed using various metaheuristic techniques, with comparative results for different systems. The inclusion of detailed MATLAB® codes in the text will assist readers—researchers, practitioners or students—to assess these techniques for different real-world systems. Thermal System Optimization is a useful tool for thermal design researchers and engineers in academia and industry, wishing to perform thermal system identification with properly optimized parameters. It will be of interest for researchers, practitioners and graduate students with backgrounds in mechanical, chemical and power engineering.
