摘要：

In the present work, the shell and tube heat exchanger (STHX) is designed based on The Tubular Exchanger Manufacturers Association standards with hot fluid (water) flowing on the shell side and cold fluid on the tube side. A comparison is made between the Nusselt number and friction factor obtained from numerical and experimental results of segmental baffles (SBs) and helical baffles (HB) with different baffle inclinations. The results show that SB provided a higher Colburn factor (j(s)) when compared with HBs STHXs (20 degrees, 30 degrees, 40 degrees, and 50 degrees), but shell side pressure drop is lower for 40 degrees HBs STHXs for the same shell side fluid flow rates.
