Carnot cycle - Wikipedia
A Carnot cycle is an ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s.
4.6: The Carnot Cycle - Physics LibreTexts
In the early 1820s, Sadi Carnot (1786−1832), a French engineer, became interested in improving the efficiencies of practical heat engines. In 1824, his studies led him to propose a hypothetical working cycle with the highest possible efficiency between the same two reservoirs, known now as the Carnot cycle.
Carnot Cycle – Definition, Processes, Components, and Limitations
2022年12月15日 · The Carnot cycle, which consists of two isothermal processes and two adiabatic processes, is the most effective heat engine cycle. The most effective heat engine cycle permitted by physical laws is the Carnot cycle. The processes involved in the heat engine cycle must be reversible and involve no change in entropy to approach the Carnot efficiency.

2024年11月7日 · Carnot cycle, in heat engines, ideal cyclical sequence of changes of pressures and temperatures of a fluid, such as a gas used in an engine, conceived early in the 19th century by the French engineer Sadi Carnot. It is used as a standard of performance of all heat engines operating between a high

The Carnot cycle is a theoretical cycle that is the most efficient cyclical process possible. Any engine using the Carnot cycle, which uses only reversible processes (adiabatic and isothermal), is known as a Carnot engine.
A Carnot cycle is a particular type of internally reversible cycle (can be a power, refrigeration, or heat pump cycle). Each of the process steps is assumed to be internally reversible, e.g.,

Carnot Cycle - HyperPhysics
The Carnot cycle can be thought of as the most efficient heat engine cycle allowed by physical laws. When the second law of thermodynamics states that not all the supplied heat in a heat engine can be used to do work, the Carnot efficiency sets the limiting value on the fraction of the heat which can be so used.
