Throttling

 

the flow of a fluid, vapor, or gas through a throttle—a local hydrodynamic resistance to a current (narrowing of a pipe, valve, or tap)—during which there is a change in pressure and temperature (the Joule-Thomson effect). The throttling effect is used mainly for copious cooling and liquefaction of gases. It is widely used to measure and regulate the consumption of liquids and gases.
