A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the number and shape of the blades. Fans have many applications including in wind tunnels and cooling towers. Design parameters include power, flow rate, pressure rise and efficiency. [1]
Ducted fans are used for propulsion or direct lift in many types of vehicle including airplanes, airships, hovercraft, and powered lift VTOL aircraft. The high-bypass turbofan engines used on many modern airliners is an example of a very successful and popular use of ducted fan design.
The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...
In the mid-1960s, Chrysler decided to adapt the 318 cu in (5.2 L) small block V8 into a lightweight, high output engine equally suited for drag strip or street performance use. Its block was bored out to 4.04 in (102.6 mm) but its 3.31 in (84.1 mm) stroke left unchanged, resulting in the 340 cu in (5.6 L) engine introduced for the 1968 model year.
Industrial fans and blowers are machines whose primary function is to provide and accommodate a large flow of air or gas to various parts of a building or other structures. This is achieved by rotating a number of blades, connected to a hub and shaft, and driven by a motor or turbine.
The Polyspheric engines were V8 engines produced by Chrysler from 1955 to 1958 as lower-cost alternatives to its Hemi engines. [1] These engines were based on the Hemi engines, using the same blocks and crankshaft parts, but completely different cylinder heads, pushrods, exhaust manifolds and pistons.
Mopar (a portmanteau of "motor" and "parts") [1] is an American car parts, service, and customer care division of the former Chrysler Corporation, now owned by Netherlands-based automobile manufacturer Stellantis. It serves as a primary OEM accessory seller for Stellantis companies under the Mopar brand.
