A Carnot heat engine [2] is a theoretical heat engine that operates on the Carnot cycle. The basic model for this engine was developed by Nicolas Léonard Sadi Carnot in 1824. The Carnot engine model was graphically expanded by Benoît Paul Émile Clapeyron in 1834 and mathematically explored by Rudolf Clausius in 1857, work that led to the ...
The first realization of a quantum heat engine was pointed out by Scovil and Schulz-DuBois in 1959, [1] showing the connection of efficiency of the Carnot engine and the 3-level maser. Quantum refrigerators share the structure of quantum heat engines with the purpose of pumping heat from a cold to a hot bath consuming power first suggested by ...
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. By Carnot's theorem, it provides an upper limit on the efficiency of any classical thermodynamic engine during the conversion of heat into work, or conversely, the efficiency of a refrigeration system in creating a temperature difference through ...
Though Carnot had developed a compelling analysis of a generalised heat engine, he had employed the clumsy and already unfashionable caloric theory. Clapeyron, in his memoire, presented Carnot's work in a more accessible and analytic graphical form, showing the Carnot cycle as a closed curve on an indicator diagram , a chart of pressure against ...
Nicolas Léonard Sadi Carnot (French: [nikɔla leɔnaʁ sadi kaʁno]; 1 June 1796 – 24 August 1832) was a French military engineer and physicist.A graduate of the École polytechnique, Carnot served as an officer in the Engineering Arm (le génie) of the French Army.
Thermodynamics, the efficiency of a Carnot heat engine, [5] or packing fraction. [6] Aeronautics, the propulsive efficiency, or percentage of chemical energy converted to kinetic energy. Chemistry, the hapticity, or the number of atoms of a ligand attached to one coordination site of the metal in a coordination compound.
A heat engine is a system that transfers thermal energy to do mechanical or electrical work. [1] [2] While originally conceived in the context of mechanical energy, the concept of the heat engine has been applied to various other kinds of energy, particularly electrical, since at least the late 19th century.
