Carnot Cycle - an overview | ScienceDirect Topics

Carnot was concerned with the important practical problem of the efficiency with which heat engines can do useful mechanical work. He envisaged an ideal heat engine (Fig. 3.19) consisting of a working substance contained in a cylinder (Y) with insulating walls and a conducting base (B) that is fitted with an insulated, frictionless piston (P) to which a variable force can be applied, a

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. Any engine that uses the Carnot cycle enjoys the maximum theoretical efficiency.

10 Difference Between Carnot Cycle And Rankine

Rankine cycle is a practical cycle of turbine and steam engine. Working Substance : Carnot cycle uses air as the working substance. Rankine cycle uses water as the working substance. Heat Addition : In Carnot cycle, heat addition is done by keeping the temperature constant. In Rankine cycle, heat addition is done by keeping pressure constant.

What is a Heat Engine? (with picture) - wiseGEEK

2021-1-14 · For example, an efficient steam engine requires both a high-temperature heat source and a low-temperature cold sink. In the Rankine cycle, a boiler makes use of a high-temperature burner to convert water into the steam. This steam goes through the engine and is then condensed back into water through a low-temperature condenser.
