Heat Exchanger / Rod baffle design
Heat Exchanger / Rod baffle design
(OP)
Hello,
To design our tubular heat-exchanger we use a HTFS software. However, we have some concern on the obtained results with a rod baffles design which are not coherent.
The software use a correlation from Phillips Petroleum compagny.
I would like to check this calculation on an excel file however despite of my serch, I don't manage to find the relevant thermal equation to calculate heat exchanged within shell.
If you have information on this subject it would be helpful.
Thank you in advance.
Nicolas

I Would also contact the software maker and discuss the problem with them .

As Unclesyd said, if you have any question do not hesitate to contact Aspentech support, they should have your answer.

Another option if you are fighting pressure drop is to use double segmental or no-tube-in-window design.

1. The big thick Heat Exchanger Design Handbook that has a chapter on longitudinal flow.
2. Articles by Gentry and Small from various symposiums and conferences in the early eighties.
