Stirling engine
Name and definition
Robert Stirling was the inventor of the first concrete manifestation of an air motor circuit closed in 1816, and it has been suggested by Fleeming Jenkin, 1884, all such engines must be generically called Stirling engines . This denomination proposal found little favor, and the different types on the market continued to be known as their individual designers or manufacturers, such as Rider's, Robinson or Heinrici engine air (hot). In the 1940s, Philips was looking for a suitable name for his own version of "air engine", which at that time, he had already been tested with other gases, and finally s establish a "Stirling engine in April 1945. However, nearly thirty years later, Graham Walker was still bemoaning the fact that terms such as "hot air engine continued to be used interchangeably with" Stirling engine ", which itself was used extensively and indiscriminately . The situation has improved somewhat, at least in the academic literature, and it is now generally accepted that "Stirling engine" should refer only to a closed-cycle regenerative heat engine with a gaseous fluid permanently work, where closed circuit is defined as a thermodynamic system in which the working fluid is permanently contained in the regeneration system and describes the use of a specific type of heat exchanger and thermal storage, called a regenerator. An engine working on the same principle but using a liquid rather than gaseous fluid existed in 1931 and was named the engine Malone.
It follows from the closed cycle operation that the Stirling engine is an external combustion engine that insulates the working fluid intake of energy supplied by an external heat source. There are many possible implementations of the Stirling engine, most of which belong to the category of reciprocating piston engine.
Functional Description
The engine is designed so that the working gas is usually compressed in the cold part of the engine and expanded in the hot resulting in a net conversion of heat into work. A regenerative heat exchanger increases the thermal efficiency of Stirling engine compared to the simple hot air engines default this feature.

Light green plunger

Link light blue handle and wheels

As a result of operating a closed cycle heat that powers a Stirling engine must be transmitted from a heat source to working fluid through heat exchangers and, finally, to a heat sink. A Stirling engine system has at least one heat source, heat sink and a maximum of five heat exchangers. Some types may be combined or waive some of these.
heat source

The heat source may be burning a fuel, and since the combustion products do not mix with the working fluid (ie, external combustion) and contact the internal moving parts of engine, a Stirling engine can run on fuels would harm others (ie, internal combustion) engines' internal, such as landfill gas containing siloxanes.
Some other suitable heat sources are concentrated solar energy, geothermal energy, nuclear energy, waste heat, or even biological. If the heat source is solar energy, solar mirrors regularly and solar dishes can be used. In addition, Fresnel lenses have been recommended t.
