In a shell- and-tube heat exchanger, which of the following tube types would be LEAST susceptible to tube-side fouling?

🔍 Key Concepts

• Tube-side fouling mechanisms (how deposits form inside tubes) • Effect of surface geometry (smooth vs. rough, added surfaces, corners) on deposit buildup • How flow velocity and turbulence inside the tube affect the tendency of materials to stick and accumulate

💭 Think About

• Think about which tube shape or surface will create more small corners, crevices, or low-velocity zones where deposits can settle and stay. • Consider which option tends to produce a smoother, more uniform internal flow path that makes it harder for fouling to adhere. • Ask yourself: do added surfaces or textures inside the tube generally increase or decrease the chance for fouling, and why?

✅ Before You Answer

• For each tube type, picture the internal surface where the fluid flows – is it mostly smooth or does it have many edges and recesses? • Compare which designs are intended mainly to improve heat transfer area vs. those that might incidentally increase fouling risk. • Verify which configuration is most likely to have uniform, higher local velocity along the tube wall, making it harder for deposits to stick.
