Baffle (liquid Mixing)
A slosh baffle is a device used to dampen the adverse effects of liquid slosh in a tank. Slosh baffles have been implemented in a variety of applications including tanker trucks, and liquid rockets, although any moving tank containing liquid may employ them. Baffle rings Baffle rings are rigid rings placed within the inside of a tank to retard the flow of liquid between sections. The location and orifice size of the rings yield varying performance for a given application. See also Baffle blocks References Fluid dynamics {{fluiddynamics-stub ...

Baffle (heat Transfer)
Baffles are flow-directing or obstructing vanes or panels used to direct a flow of liquid or gas. It is used in some household stoves and in some industrial process vessels (tanks), such as shell and tube heat exchangers, chemical reactors, and static mixers. Baffles are an integral part of the shell and tube heat exchanger design. A baffle is designed to support tube bundles and direct the flow of fluids for maximum efficiency. Baffle design and tolerances for heat exchangers are discussed in the standards of the Tubular Exchanger Manufacturers Association (TEMA). Use of baffles The main roles of a baffle in a shell and tube heat exchanger are to: * Hold tubes in position (preventing sagging), both in production and operation * Prevent the effects of steam starvation, which is increased with both fluid velocity and the length of the exchanger * Direct shell-side fluid flow along the tube field. This increases fluid velocity and the effective heat transfer co-efficient of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baffle (medicine)
A baffle is a surgically created tunnel or wall within the heart or major blood vessels used to redirect the flow of blood. They are used in some types of heart abnormalities that a child is born with known as congenital heart defects. Baffles are usually constructed, at least in part, from a person's own heart tissue, while other methods of redirecting blood using artificial material are known by the more generic term 'conduits'. Baffles can be made between different structures depending on the heart condition that needs to be treated. Dextro-transposition of the great arteries In dextro-transposition of the great arteries, at the initial arterial switch a Jatene procedure is normally done in conjunction to switch the coronary arteries as well, as they originate from the aorta. The Jatene procedure is ideally performed during the second week of life, before the left ventricle adjusts to the lower pulmonary pressure. In cases where the Jatene is not performed in time, the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baffles (submarine)
The baffles is the area in the water directly behind a submarine or ship through which a hull-mounted sonar cannot hear. This blind spot is caused by the need to insulate the sonar array, commonly mounted near the bow, from the noise of the vessel's machinery. During the Cold War, one submarine would frequently attempt to follow another by hiding in its baffles. This led to the practice of "clearing the baffles", that is, turning to observe the blind spot and detect any followers. Related maneuvers included the "Crazy Ivan", a hard turn to clear the baffles and position the submarine to attack any followers, and "Angles and Dangles", a five-hour process of rapid direction and speed changes to ensure that all items aboard were properly secured for hard maneuvering and would not fall or shift suddenly, producing noise that the enemy could detect. The baffles-clearing maneuvers undertaken by Soviet ''Yankee''-class submarines were dubbed "Yankee Doodles". Hiding in a sub's ...
