    Exhaustive analysis of air-side average heat transfer coefficients, system thermal resistances, and ground-side thermal resistances provide quantitative design information for future applications. Finned and unfinned versions of the device permit assessment of fin performance on both ground-side and air-side heat transfer.

      The Free‐Piston Stirling Power Converter (FPSC) is one of the many power technologies being evaluated and developed by NASA. FPSPCs have the potential to provide high reliability, long life, efficient operation; and they can be coupled with all potential heat sources, nuclear, radioisotope and solar, various heat input, heat rejection systems. Such tools facilitate the computations and enable us to determine the potential of the explored area and/or to select appropriate operational parameters of given geothermal installation in order to ensure its long life and failureless running [41,42,43]. Available numerical simulators for geothermal applications are mainly based on two.

    Stirling engine technology has been selected by General Motors for development in the U.S. Department of Energy (DOE) hybrid electric vehicle (HEV) program, which is in its initial engine evaluation. Much will be learned about the potential of the Stirling engine for possible application to the PNGV program through this program.

STIRLING ENGINE - AVAILABLE TOOLS FOR LONG-LIFE ASSESSMENT Gary R. Halford and Paul A. Bartolotta National Aeronautics and Space Administration Lewis Research Center Cleveland, Ohio Abstract A review is presented of the durability approaches applicable to long-time life assessment of Stifling engine hot-section components.

Get this from a library. Stirling engine -- available tools for long-life assessment. [Gary R Halford; Paul A Bartolotta; United States. National Aeronautics and Space Administration.]. Appropriately designed, the Stirling engine promises high thermal efficiency, quiet operation and the ability to operate from a wide range of heat sources.

Stirling Cycle Engines offers tools for expediting feasibility studies and for easing the task of designing for a novel application. Stirling engines work using the heat energy as the energy input and are based on the Stirling cycle.

It is proposed to develop a Stirling engine for a kW e electrical output. Definition: A Stirling engine is a thermal machine that transforms heat into work to produce electricity. The engine operates on a thermodynamic cycle, with compression and expansion of the working fluid at different temperature levels.

Attractive Stirling Properties. Stirling engine Technological Needs. Multi-fuel capability 2. Waste heat. Stirling engines have a major advantage over other comparative processes in that the combustion here occurs in an external combustion engine.

This minimizes the level of purification required for LFG compared with other utilization processes. Stirling engines can be successfully combined for CHP systems to provide a high thermal efficiency.

A recent scaling study on a free-piston Stirling engine highlights the leakage losses as one of the main bottlenecks [39]. The increased leakage loss induces reheat losses due to the flow of cold.

Revival of the Stirling engine. The Stirling engine had attracted attention again aroundafter Philips co. had started to develop the Stirling as a portable electric power generator.

At the same time, the Stirling engine was being researched as a refrigerator. It succeeded in that it cools even 74 K. Alpha type: Alpha Stirling engines have two power pistons in separate cylinders installed at either side of the cooler, regenerator and heater, as depicted in Fig.

1(a). Both pistons need to transfer the work and have to be sealed to contain the high pressure working gas. The alpha type Stirling engine can be arranged in a double-acting configuration by interconnecting several alpha units in a.

The NASA Lewis Research Center is conducting technology development for Stirling convertors directed toward a dynamic power source for space applications.

Space power requirements include high reliability with very long life, low vibration and high system. At Longlife Stirling we offer stainless steel exhausts, custom exhausts systems, performance exhausts systems, Fife Auto Centre (Stirling), car tuning, engine remapping, Audi, BMW, VW, performance parts and.

The innovation is a small, highly efficient, long life, low mass free-piston Stirling engine for low power applications. This machine is innovative because in addition to its small mass and physical dimensions it is anticipated to have 35 percent higher efficiency than engines now being considered by NASA.

Heat pumps are increasingly seen as efficient and cost-effective heating systems also in industrial applications. They can drastically reduce the carbon footprint of heating by utilizing waste heat and renewable electricity.

Recent research on Stirling cycle-based very high temperature heat pumps is motivated by their promising role in addressing global environmental and energy-related challenges. A conceptual design of a free piston solar Stirling engine-linear alternator which can be designed and developed to meet the requirements of a near-term solar test bed engine with minimum risks was developed.

The conceptual design was calculated to have an overall system efficiency of 38% and provide 15kW electric output.

The early Stirling engine had a history of good service and long life up to 20 years. It was used as a relatively low-power water-pumping engine from the middle of the nineteenth century to aboutwhen the internal combustion engine and the electric motor replaced it.For Stirling engines to enjoy widespread application and dcceptance, not only must the fundamental operation of such engines be widely understood, but the requisite analytic tools for the simulation, design, evaluation and optimization of Stirling engine hardware must be readily available.The purpose of this design manual is to provide an introduction to Stirling cycle heat engines, to organize and identify the available Stirling engine literature, and to identify, organize.
