Stirling And Thermal Lag Engines Motive Power Without The Co2

Existing literature focuses on the alleged merits of the Stirling engine. These are indeed latent but, decades on, remain to be fully realised. This is despite the fact that Stirling and other closed-cycle prime-movers offer a contribution to an ultra-low carbon economy. By contrast with solar panels, the initial manufacture of Stirling engines makes no demands on scarce or exotic raw materials. Further, calculating embodied carbon per kWh favours the Stirling engine by a wide margin.However, the reader expecting to find the Stirling engine promoted as a panacea for energy problems may be surprised to find the reverse. Stirling and Thermal-Lag Engines reflects upon the fact that there is more to be gained by approaching its subject as a problem than as a solution. The Achilles heel of the Stirling engine is a low numerical value of specific work, defined as work per cycle per swept volume per unit of charge pressure and conventionally denoted Beale number NB. Measured values remain unimproved since 1818, quantified here for the first time at 2% of the NB of the modern internal combustion engine! The low figure is traced to incomplete utilisation of the working gas. Only a small percentage of the charge gas — if any — is processed through a complete cycle, i.e., between temperature extremes.The book offers ready-made tools including a simplified algorithm for particle trajectory map construction; an author-patented mechanism delivering optimised working-gas distribution; flow and heat transfer data re-acquired in context and an illustrated re-derivation of the academically respected Method of Characteristics which now copes with shock formation and flow-area discontinuities. All formulations are presented in sufficient detail to allow the reader to 'pick up and run' with them using the data offered in the book.The various strands are drawn together in a comprehensively engineered design of an internally focusing solar Stirling engine, presented in a form allowing a reader with access to basic machining facilities to construct one.The sun does not always shine. But neither will the oil always flow. This new title offers an entrée to technology appropriate to the 21st century.

ENERGY SYSTEMS Reimagine the future of energy production and use with this innovative and state-of-the-art guide This multidisciplinary and comprehensive text features an up-to-date summary of salient energy technologies for quick reference by students and practitioners of energy engineering. Uniquely, the book employs a guided self-study approach with theory provided in “bite-sized” chunks, several worked examples, quantitative and qualitative practice problems, 10 real-world mini-projects, and interviews with young energy innovators and engineering students. The book poses many big and pressing questions, asking the reader to “reimagine our future,” particularly with a focus on sustainable energy. These questions are aligned with characteristics of an entrepreneurial mindset, which are emphasized throughout the book. The book reviews the fundamentals of thermodynamics, fluid mechanics, and quantum mechanics. Chapters explore the full range of energy conversion technologies, including energy supply and demand, the science of global warming, interpretations of sustainability, chemical fuels, carbon capture and storage, internal and external combustion engines, vapor power and refrigeration plants, nuclear power, solar-electricity, solar-heat, fuel cells, wind energy, water energy, and energy storage. The book ends with a brief investigation into what we can do to decarbonize the transportation, industry, buildings, and electric power sectors. Energy Systems: A Project-Based Approach to Sustainability Thinking for Energy Conversion Systems offers an accessible overview of this important subject with an innovative, easy-to-use organization. Built to facilitate active learning and representing the latest research and industrial practice, Energy Systems provides readers with tools and information to evaluate energy systems and to reimagine potential energy solutions. Readers of Energy Systems will also find: Organization designed to blend seamlessly with a 14-week course schedule A balance of robust theoretical and industry-related knowledge and real-world examples throughout Teaching resources including mini-projects, practice problems, remedial appendices, and online study notes Energy Systems is ideal for students and instructors in courses relating to Energy Conversion Systems, Energy Science, Sustainable/Renewable Energy, and the interrelated Social, Technological, Economic, Environmental, and Political aspects. The book will also appeal to practitioners of energy engineering via the numerous state-of-the-art summaries and real-world problems.

Two centuries after its original invention, the Stirling engine has finally emerged as a commercial reality. Providing an alternative to centralized power generation, the Stirling is now employed as the core component in domestic CHP (combined heat and power) technology, which offers substantial savings in raw energy utilization and in doing so also addresses current concerns regarding hydrocarbon consumption and greenhouse gas emissions. The successful use of the Stirling requires the addressing of a range of issues, including the long-standing mismatch between inherently favorable internal efficiency and wasteful external heating provision; the dearth of data on heat transfer and flow related to the task of first-principles design; and its limited RPM capability when operating with air (and nitrogen) as working fluids. All of these matters are explored in depth in The Air Engine: Stirling Cycle Power for a Sustainable Future. The account also includes previously unpublished insights into the character and potential deployment of two related engines -- the pressure-wave and thermal-lag.

A lucid introduction to the Stirling Engines, written primarily for laymen with little back ground in Mechanical Engineering. The book covers the historical aspects, the conceptual details as well as the brief steps in making a simple working Stirling Engine model.
