In a multipass shell and tube heat exchanger, the baffles on shell side is primarily provided for______________?
Correct answer: D. Creating turbulence
- A. Reducing scale deposition
- B. Increasing pressure drop
- C. Fixing the tubes
- D. Creating turbulence
Explanation
Shell-side baffles force the fluid to flow across the tubes rather than straight along the shell, increasing mixing and turbulence and therefore improving the heat-transfer coefficient. They also provide tube support, but turbulence creation is the primary purpose here.
