Short velocity stacks on a 302 cu.in. Ford FE engine in the tight confines of a Ford GT-40. A velocity stack, trumpet, or air horn [1] is a typically flared, parallel-sided tubular device fitted individually or in groupings to the entry of an engine's air intake system to smooth high speed airflow, and allow engine intake track tuning to incorporate pressure pulses created by its internal ...
An ejector or jet venturi scrubber is an industrial pollution control device, usually installed on the exhaust flue gas stacks of large furnaces, but may also be used on any number of other air exhaust systems. They differ from other venturi scrubbers energy is derived from the high-pressure spray of liquid from a nozzle rather than the flow of ...
Cosworth Formula One engine, with bell-mouthed inlet trumpets for each cylinder, known as a velocity stack. A bell-mouth inlet duct is a form of convergent inlet air duct used to direct air into the inlet of a gas turbine engine. The area of a convergent duct gets smaller as the air flows into the engine.
The limiting case of the Venturi effect is when a fluid reaches the state of choked flow, where the fluid velocity approaches the local speed of sound. When a fluid system is in a state of choked flow, a further decrease in the downstream pressure environment will not lead to an increase in velocity, unless the fluid is compressed.
ejector venturi scrubber; A system may include one or multiple of these components in addition to various supporting components such as: Ductwork and fan system; A saturation chamber (optional) Entrainment separator or mist eliminator; Pumping (and possible recycle system) Spent scrubbing liquid treatment and/or reuse system; An exhaust stack
The strength of the vacuum produced depends on the velocity and shape of the fluid jet and the shape of the constriction and mixing sections, but if a liquid is used as the working fluid, the strength of the vacuum produced is limited by the vapor pressure of the liquid (for water, 3.2 kPa or 0.46 psi or 32 mbar at 25 °C or 77 °F). If a gas ...
The velocity of the air flow entering the carburetor is measured by placing one or more venturi directly in the airflow. The venturi creates a low pressure that changes with the velocity of the air. As the air pressure in chamber A is decreased with greater airflow, the diaphragm is pulled toward the carburetor body.
In a simple spray tower, the velocity of the particulates in the gas stream is low: 0.6 to 1.5 m/s (2 to 5 ft/s). By introducing the inlet gas tangentially into the spray chamber, the cyclonic scrubber increases gas velocities (thus, particulate velocities) to approximately 60 to 180 m/s (200 to 600 ft/s).
