Hot air engines, often called Stirling engines, are among the most interesting and intriguing engines ever to be designed. They run on just about any fuel, from salad oil and hydrogen to solar and geothermal energy. They produce a rotary motion that can be used to power anything, from boats and buggies to fridges and fans. This book demonstrates how to design, build, and optimise Stirling engines. A broad selection of Roy’s engines is described, giving a valuable insight into the many different types and a great deal of information relating to the home manufacture of these engines is included in the workshop section.

Chapters: Carnot heat engine, Crookes radiometer, Stirling engine, Applications of the Stirling engine, Thermoacoustic hot air engine, Rijke tube, Thermomechanical generator, Fluidyne engine, Stoddard engine, Photo-Carnot engine. Excerpt: A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. Like the steam engine, the Stirling engine is traditionally classified as an external combustion engine, as all heat transfers to and from the working fluid take place through the engine wall. This contrasts with an internal combustion engine where heat input is by combustion of a fuel within the body of the working fluid. Unlike a steam engine's (or more generally a Rankine cycle engine's) usage of a working fluid in both its liquid and gaseous phases, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air. Typical of heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. The efficiency of the process is narrowly restricted by the efficiency of the Carnot cycle, which depends on the temperature difference between the hot and cold reservoir. Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century. The Stirling engine is noted for its high efficiency compared to steam engines, quiet operation, and the ease with which it can use almost any heat source. This compatibility with alternative and renewable energy sources has become increasingly significant as the price of conventional fuels rises, and also in light of conc...

Two centuries after the original invention, the Stirling engine is now a commercial reality as the core component of domestic CHP (combined heat and power) – a technology offering substantial savings in raw energy utilization relative to centralized power generation. The threat of climate change requires a net reduction in hydrocarbon consumption and in emissions of 'greenhouse' gases whilst sustaining economic growth. Development of technologies such as CHP addresses both these needs. Meeting the challenge involves addressing a range of issues: a long-standing mismatch between inherently favourable internal efficiency and wasteful external heating provision; a dearth of heat transfer and flow data appropriate to the task of first-principles design; the limited rpm capability when operating with air (and nitrogen) as working fluid. All of these matters are explored in depth in The air engine: Stirling cycle power for a sustainable future. The account includes previously unpublished insights into the personality and potential of two related regenerative prime movers - the pressure-wave and thermal-lag engines. Contains previously unpublished insights into the pressure-wave and thermal-lag engines Deals with a technology offering scope for saving energy and reducing harmful emissions without compromising economic growth Identifies and discusses issues of design and their implementation

The original Air Engines (also known as a heat, hot air, caloric, or Stirling engines), predated the modern internal combustion engine. This early engine design always had great potential for high efficiency/low emission power generation. However, the primary obstacle to its practical use in the past has been the lack of sufficiently heat resistant materials. This obstacle has now been eliminated due to the higher strength of modern materials and alloys. Several companies in the U.S. and abroad are successfully marketing new machines based on the Air Engine concept. Allan Organ and Theodor Finkelstein are two of the most respected researchers in the field of Air Engines. Finkelstein is considered a pioneer of Stirling cycle simulation. The historical portion of the book is based on four famous articles he published in 1959. The rest of the chapters assess the development of the air engine and put it in the modern context, as well as investigate its future potential and applications. The audience for this book includes mechanical engineers working in power related industries, as well as researchers, academics, and advanced students concerned with recent developments in power generation.

Do you know how to make a working engine from soda cans? You do now! The Quick and Easy Stirling Engine book will show you every detail you need to know. There are no difficult secrets and no expensive parts to buy. With two soda cans and a few other materials you can build a running engine in just a few hours. The engine featured in this book was designed for use in educational settings. Consulting with several educators, this engine was designed so that it could be assembled with simple hand tools by most builders in about three hours. The parts list is simple and affordable. Simple hand tools are all that is required for assembling this engine. Once assembled, the engine will spin a flywheel when the bottom is heated and ice is placed on top. This is a hot air engine design, sometimes referred to as a Stirling Engine. The engine makes motion by exercising a temperature differential. The bottom half of the engine must be warmed to about 250 degrees F, and the top of the engine must be cooled with cold water or ice. When these conditions are present, the engine will spin between 100 and 200 rpm. The primary components of this engine are soda cans, copper wire, and an old CD. The adhesive that is used for construction is readily available at hardware stores. This engine is a fun project for students, home builders, hobbyists, and anyone who wants to learn how to make their own hot air engine from soda cans.

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'.

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.
