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 vibration, 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 promote mixing.
In a chemical reactor, baffles are often attached to the interior walls to promote mixing and thus increase heat transfer and possibly chemical reaction rates. ...

Famous quotes containing the word baffles:
“I have heard that whoever loves is in no condition old. I have heard that whenever the name of man is spoken, the doctrine of immortality is announced; it cleaves to his constitution. The mode of it baffles our wit, and no whisper comes to us from the other side. But the inference from the working of intellect, hiving knowledge, hiving skill,at the end of life just ready to be born,affirms the inspirations of affection and of the moral sentiment.”
—Ralph Waldo Emerson (18031882)
