Stirling engine

n.
A heat engine driven by a permanently enclosed gas that expands and contracts as it is alternately heated and cooled by an external source of heat and a heat exchanger.

[After the Reverend Robert Stirling (1790-1878), Scottish clergyman and engineer who invented it.]

Stirling engine

n
(Mechanical Engineering) an external-combustion engine that uses air or an inert gas as the working fluid operating on a highly efficient thermodynamic cycle (the Stirling cycle)

He is an expert in stirling engines, concentrated solar power systems, and optimization of thermal/fluid/energy devices.
"At the moment, the technologies for manufacturing external combustion engines, the so-called Stirling engines, are being developed and are being implemented, including the receipt of the necessary energy components from solid or liquefied energy carriers," Denisov said.
Each Thalis SolarDish 751S generator uses solar energy converted into heat to produce electricity with the use of two free piston Stirling engines generators, a thermal storage device, a dish -- a solar concentrator spanning around 10 metres -- a tracking device and a heat receiver and transfer tube.
It is believed that this storage solution combined with CleanergyA[sup.3]s highly efficient Stirling engines will produce scalable and dispatchable renewable electricity at very competitive cost, thanks to the system's modular design.
On the other hand, a pure mechanical engineering solution should be applied to air conditioning to reducing energy consumption as replacing compressor by Stirling engine. Stirling engines are significant for low pollution and small noise, since the vibration is very low, with higher durability, simple structure, and capability to self-start; for these reasons, it can be used for air conditioning.
The results from above researches showed that, the solutions of TEG, ORC, ETC, compressor-turbocharger, Stirling engines, exhaust boiler, absorbent refrigerator for recovering the WH from diesel engines are popular.
Figure 2 provides expected temperature trace of kiloPower reactor subjected to sudden loss of 25% of Stirling engines, a rather large power mismatch between the core and the power conversion system.
About 50 years ago the US car giants General Motors and Ford decided independently to look into the viability of replacing the existing petrol car engines by Stirling engines as a means to improve fuel economy and reduce pollution.
Bergthorson and his colleagues described their work in a paper that appeared last December in Applied Energy but acknowledges that this concept catches many people off guard, especially if they are unfamiliar with closed-cycle power plants such as Stirling engines that could function indefinitely on a limited supply of metal fuel.
On a longer-range basis, the diesel and the Stirling engines offer the greatest potential because historically there is already an appreciable amount of experience with these engines.
