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 [ 1 ] and in some industrial process vessels (tanks), such as shell and tube heat exchangers , chemical reactors , and static mixers .
Baffle (liquid mixing), auxiliary devices employed in tank which suppress the effects of slosh dynamics; Baffle (heat transfer), a flow-directing or obstructing vane or panel used in some industrial process vessels (tanks) Baffle (medicine), a tunnel or wall surgically constructed within the heart or primary blood vessels to redirect blood flow
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.
Important examples include propellant slosh in spacecraft tanks and rockets (especially upper stages), and the free surface effect (cargo slosh) in ships and trucks transporting liquids (for example oil and gasoline). However, it has become common to refer to liquid motion in a completely filled tank, i.e. without a free surface, as "fuel slosh".
Cylindrical tanks require full-length vanes since a portion of the propellant could adhere to the forward tank head. Spherical tanks need full-length vanes in a case by case basis. If the acceleration is lateral, partial-length vanes can work. [5]: 5 A center post can be added to the tank in addition to the side vanes.
Antiroll tanks are tanks fitted onto ships in order to improve the ship's response to roll motion. Fitted with baffles intended to slow the rate of water transfer from the port side of the tank to the starboard side and the reverse, the tanks are designed such that a larger amount of water is trapped on the higher side of the vessel.

A newly set up baffle filter, under a large volume cichlid aquarium. Baffle filters are similar to wet and dry, trickle filters in that they are generally situated below the aquarium. This type of filter consists of a series of baffles that the water must pass through in order to reach the pump which is returning water to the aquarium.
