About RINGBOM STIRLING ENGINES (from the Publisher):
******The Ringbom engine, an elegant simplification of the Stirling engine, 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 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.******
About STIRLING ENGINES (from Wikipedia):
************A Stirling engine is a heat engine that is operated by the cyclic compression and expansion of air or other gas (the working fluid) between different temperatures, resulting in a net conversion of heat energy to mechanical work. More specifically, the Stirling engine is a closed cycle regenerative heat engine, with a permanent gaseous working fluid. Closed cycle, in this context, means a thermodynamic system in which the working fluid is permanently contained within the system. Regenerative describes the use of a specific type of internal heat exchanger and thermal store, known as the regenerator. Strictly speaking, the inclusion of the regenerator is what differentiates a Stirling engine from other closed cycle hot air engines.******
