joule's cycle Meaning
joule's cycle ()
The cycle for the air engine proposed by Joule. In it air is taken by a pump from a cold chamber and compressed adiabatically until its pressure is eqal to that of the air in a hot chamber, into which it is then delivered, thereby displacing an equal amount of hot air into the engine cylinder. Here it expands adiabatically to the temperature of the cold chamber into which it is finally exhausted. This cycle, reversed, is used in refrigerating machines.
joule's cycle Sentence Examples
- Joule's cycle is a theoretical reversible thermodynamic cycle that describes the conversion of heat into mechanical work.
- The Joule's cycle consists of four processes: isothermal compression, adiabatic compression, isothermal expansion, and adiabatic expansion.
- The isothermal processes in Joule's cycle are carried out at constant temperature, while the adiabatic processes are carried out without heat transfer.
- The work done by the system during the isothermal expansion is greater than the work done on the system during the isothermal compression.
- The net work done by the system during the Joule's cycle is equal to the difference between the work done during the isothermal expansion and the work done during the isothermal compression.
- The efficiency of Joule's cycle is given by the ratio of the net work done by the system to the heat absorbed by the system during the isothermal expansion.
- The efficiency of Joule's cycle is always less than 100%, due to the irreversibility of the processes involved.
- Joule's cycle is used to model the operation of heat engines and refrigerators.
- The Joule-Thomson effect is a thermodynamic phenomenon that describes the change in temperature of a gas when it is throttled through a porous plug.
- The Joule-Thomson effect is used in the operation of liquefiers and refrigerators.
