baffle

a plate or mechanical device designed to restrain or regulate the flow of a fluid, the emission of light or sound, or the distribution of sound, esp in a loudspeaker or microphone

Baffle

An opaque or translucent element used to diffuse or shield a surface from direct or unwanted light.

Baffle

 

an installation in the afterbay of an overflow dam that changes the direction of the flow and spreads the width of the water stream when only some of the spillway apertures in the dam are functioning. The basic purpose of a baffle is to ensure a fairly uniform distribution of the flow velocities and to reduce them on the downstream apron. A distinction is made between a ramp baffle (continuous or slotted), which is installed along the entire width of the water apron, and a baffle formed of piers, which is placed at an angle to the water stream.

baffle
i. A series of partitions in a fuel tank to control the rapid flow of fuel and prevent its sloshing. These partitions have holes that allow the fuel to feed to the tank outlet, but they keep the fuel from surging enough to uncover the fuel outlet.
ii. A partition separating the upper portion of the tank that prevents oil pump cavitation as oil tends to rush to the top of the tank during deceleration periods. The baffle is fitted with a weighted swirl outlet control valve that is free to swing below the baffle. The valve closes when oil at the bottom of the tank rushes up when the aircraft decelerates.
iii. A sheet metal shield used to direct the flow of air between and around the cylinders of an air-cooled reciprocating engine.
iv. A partial partition in the pitot system to trap moisture and any solid matter as well as to reduce turbulence.
