Electromagnets are used in all kinds of electric devices, including hard disk drives, speakers, motors, and generators, as well as in scrap yards to pick up heavy scrap metal. They're even used in MRI machines, which utilize magnets to take photos of your insides
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 tube field. This increases fluid velocity and the effective heat transfer co-efficient of the exchanger
In a static mixer, baffles are used to minimize tangential component of velocity which cause vortex formation thus promote mixing.[1]
In a chemical reactor, baffles are often attached to the interior walls to promote mixing[2] and thus increase heat transfer and possibly chemical reaction rates.
Implementation of baffles is decided on the basis of size, cost and their ability to lend support to the tube bundles and direct
Longitudinal Flow Baffles (used in a two-pass shell)
Impingement Baffles (used for protecting bundle when entrance velocity is high)
Orifice Baffles
Single segmental
Double segmental
Support/Blanking baffles
Deresonating (detuning) baffles used to reduce tube vibration
