Thermodynamics

A fluid cooled by squeezing it through a restriction

In thermodynamics, throttling is the irreversible expansion of a fluid forced through a restriction (a valve, porous plug, or narrow opening), which drops its pressure at essentially constant enthalpy, with no work done and no heat exchanged. Joule and Thomson's porous-plug experiments showed that real gases change temperature on such expansion, the Joule-Thomson effect that underlies gas liquefaction and refrigeration. The referent is an isenthalpic pressure-drop process, related to the engine and software meanings only by the shared idea of restricting a flow.[1]

Unit
The pressure drop and the temperature change across the restriction
