throttling process فراروند ِ تاسنش farâravand-e tâseneš Fr.: 1) détente Joule-Thomson Thermodynamics: A process in which a gas, originally at a constant high
pressure, passes → adiabatically through a porous wall or a narrow opening into a region of constant lower
pressure. The throttling process is → irreversible
and is accompanied by an increase of → entropy.
The → enthalpy of the gas is the same in the
→ initial and
→ final → states.
Also called → Joule-Thomson expansion.
The change in the temperature of the gas in throttling is known as
the → Joule-Thomson effect.
A technique implemented in the architecture of computers whereby the
frequency produced by the microprocessor is automatically
adjusted. Throttling process allows the computer to conserve power and also reduce the heat generated by its chip.
