Correct Answer: D. All of the above
🔍 Explanation:
Baffles in a shell and tube heat exchanger serve multiple important functions, including:

🔸 A. Facilitate the cleaning of outer tube surface
Baffles direct the shell-side fluid flow across the tubes (instead of straight-through), which helps prevent fouling and keeps the outer surface cleaner.

🔸 B. Enhance turbulence
By forcing the shell-side fluid to flow transversely over the tubes, baffles increase turbulence, improving the heat transfer coefficient.

🔸 C. Hold the tubes in position
Baffles support the tubes mechanically, preventing sagging or vibration due to fluid flow or thermal expansion.

✅ Therefore, the most comprehensive and correct choice is:
