If the throttling valve or device is located at the entry into a pressure vessel so that the flash evaporation occurs within the vessel, then the vessel is often referred to as a flash drum. [1] [2] If the saturated liquid is a single-component liquid (for example, propane or liquid ammonia), a part
Dynamic frequency scaling (also known as CPU throttling) is a power management technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly" depending on the actual needs, to conserve power and reduce the amount of heat generated by the chip.
In practice, the Joule–Thomson effect is achieved by allowing the gas to expand through a throttling device (usually a valve) which must be very well insulated to prevent any heat transfer to or from the gas. No external work is extracted from the gas during the expansion (the gas must not be expanded through a turbine, for example).
Examples include the balanced "double beat" type used on Gresley A3 Pacifics. Throttling of a rocket engine means varying the thrust level in-flight. This is not always a requirement; in fact, the thrust of a solid-fuel rocket is not controllable after ignition, and is instead pre-planned by varying the shape of the void down the center of the ...
Flash evaporation (or partial evaporation) is the partial vaporization that occurs when a saturated liquid stream undergoes a reduction in pressure by passing through a throttling valve or other throttling device. This process is one of the simplest unit operations, being equivalent to a distillation with only one equilibrium stage.
This plot device is generally believed to have been popularized by movie serials and 19th-century theatrical melodramas. A well-known example is the cliché of the moustache-twirling villain leaving the heroine tied to railroad tracks.
Absurdist fiction is a genre of novels, plays, poems, films, or other media that focuses on the experiences of characters in situations where they cannot find any inherent purpose in life, most often represented by ultimately meaningless actions and events that call into question the certainty of existential concepts such as truth or value.

The devices shown are on steam engines. Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid (steam) supplying the prime mover. As the speed of the prime mover increases, the central spindle of ...
