What is Stirling engine

In a Stirling engine, heat energy is converted to mechanical work through the cyclic compression and expansion of air or another gas (the working fluid) at varying temperatures.

To be more precise, the Stirling engine uses a permanently gaseous working fluid and is a closed-cycle regenerative heat engine. Regenerative refers to the employment of a certain kind of internal temperature exchanger and thermal store, known as a regenerator, while closed-cycle refers to a thermodynamic system in which the working fluid is permanently confined within the system. The regenerator is what, strictly speaking, sets a Stirling engine apart from other closed-cycle heat engines.

What are the Usage for Stirling engines？

1. Cogeneration (CHP)- A Stirling engine can exploit the waste heat produced by the second law of thermodynamics in a cogeneration unit. This waste heat may power the Stirling engine for industrial or agricultural applications.

2. Solar energy generation- Stirling engines can convert sun energy into electricity more efficiently than some photovoltaic cells when positioned at the primary of a parabolic mirror, as seen in the figure below.

3. Submarines- Compared to traditional submarines, Stirling-powered submarines have a significantly longer underwater lifespan. Stirling engines, which allow the submarine to stay underwater for days or weeks at a time without having to surface to recharge its batteries, were initially placed in submarines by Swedish shipbuilder Kockums.

Nuclear power plants—Stirling engines have the potential to replace steam turbines in nuclear reactors, improving plant efficiency and lowering radioactive byproducts. These engines would also eliminate the need for water at any point in the cycle by using liquid sodium as cooling.

4, Educational demonstration- A slight variation in temperature Any small temperature differential will cause a Stirling engine to operate, such as the one seen in between a hand's palm. A Stirling engine with a low-temperature differential (LTD) may produce about 1 W of power from a person's palm.
