He_design_stirling_engine.pdf. Stirling engine. Alpha type Stirling engine. There are two cylinders. The expansion cylinder (red) is maintained at a high temperature while the compression cylinder (blue) is cooled. The passage between the two cylinders contains the regenerator. Beta type Stirling engine. There is only one cylinder, hot at one end and cold at the other. A loose fitting displacer shunts the air between the hot and cold ends of the cylinder. Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.[3] The Stirling engine is noted for its high efficiency compared to steam engines,[4] quiet operation, and the ease with which it can use almost any heat source.
Name and classification[edit] There are many possible implementations of the Stirling engine most of which fall into the category of reciprocating piston engine. History[edit] Invention and early development[edit] Later nineteenth century[edit] Tesla turbine. Tesla turbine The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine, cohesion-type turbine, and Prandtl layer turbine (after Ludwig Prandtl). Bioengineering researchers have referred to it as a multiple disk centrifugal pump.[1][2] One of Tesla’s desires for implementation of this turbine was for geothermal power, which was described in "Our Future Motive Power".[3] Description[edit] View of Tesla turbine "bladeless" design Tesla wrote, "This turbine is an efficient self-starting prime mover which may be operated as a steam or mixed fluid turbine at will, without changes in construction and is on this account very convenient.
This turbine can also be successfully applied to condensing plants operating with high vacuum. Pump[edit] Tesla Other. Jeff Hayes on how a Tesla Turbine works. Jeff Hayes on how a Tesla Turbine works.
