Stirling Articles & Analysis

Finite–time thermodynamics takes into account exo–irreversibilities which are not managed by reversible thermodynamics, especially reservoir–to–gas temperature gaps. In today's works, thermodynamicists use the working gas mass as the main imposed parameter. In this paper, the study of the Stirling engine cycle is carried out with a motorist–oriented viewpoint: instead of the working gas mass, the ...

A detailed design optimisation study of an endo- and exoirreversible Stirling engine is carried out. After energetic, entropic and exergetic analyses of the hot-end and cold-end heat exchangers of the engine, an adapted model of the engine, including the heat exchangers and the regenerator, is proposed to optimise the distribution of the limited heat exchangers' total area. Power generation, ...

A Qnergy Stirling-Based Power Generator reached 20,000 hours (more than two continuous years) of uninterrupted, maintenance-free operation. About five times longer than conventional generators. The generator is installed in the IJ & Jeanné Wagner Jewish Community Center in Salt Lake City, Utah (JCC). It uses Qnergy’s proprietary Free-Piston Stirling technology. The same ...

Stirling engines are heat engines that operate on a closed thermodynamic regenerative cycle and are used as power systems, refrigerators or heat pumps. Recent developments in Stirling technology allow the use of low temperature heat sources including flat plate solar collectors. New concepts for low-cost, low ΔT Stirling engines that may be made by village craftsmen using locally available ...

With some of the highest levels of Direct Normal Irradiance (DNI) in the world, CSP is positioned to play an immense role in South Africa’s energy landscape. Currently, four CSP technologies are being promoted internationally, parabolic trough, power tower, fresnel and dish stirling, but with the lack of operational data in South Africa the industry is still evaluating the suitability of ...

On June 18, 2015, the U.S. Department of Energy (DOE) announced $55 million in funding for projects to accelerate biomass development and develop generator technologies under the Advanced Research Projects Agency-Energy (ARPA-E). The funding will be divided between two of ARPA-E's programs, GENerators for Small Electrical and Thermal Systems (GENSETS) and Transportation Energy Resources from ...

The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

THE BENEFITS OF SOLAR THERMAL POWER PLANTS Solar thermal energy production requires two main things: sunlight and equipment to capture, store and disperse the energy. Only two types of solar thermal systems exist. They are the passive systems, which do not require equipment (such as the heat build-up in your car whenever you park it in the sun), and active systems which require a method to ...
