I want to try simulating a shell and tube heat exchanger using aspen. What are the parameters needed to start the simulation? Please advise me regarding this.

The exact same parametrs you need to design it by hand.

Have you even sat in front of the aspen control? It asks for all the inputs right in front of you.

Thanks for your reply. Previously I go through heat exchanger simulation with no phase change using the basic heat exchanger calculation. Can I use the same for shell and tube heat exchanger?

Use Aspen HTFS to do the simulation.

Dear all,

I was trying to size the shell and tube heat exchanger for condensation service. On the shell side i have mixture of light alcohols and on tube side cooling water. I tried to rate exchanger in simulators, and heat exchanger softwares which are available commercially but what i observed is interesting.
The overall heat transfer coefficient for vertical and Horizontal condenser was almost equivalent, which should not be a case.
Can anybody tell me that whether i am doing a mistake or this is a problem or a bug in these softwares.
Cheers!!

Sir

I want to study some tutorials on HTFS for heat exchanger simulation. Can u provide me any link to download HTFS tutorials...

Thank you

I have a sentence in PERRY's CHEMICAL ENGINEERS' HANDBOOK seems related to it;
"At high condensing loads, with vapor shear dominating, tube orientation has no effect, and..."(5-22 page)

Dear Zauberberg,
Could you please recheck the link as it doesn't work with me. Thanks in advance and have a nice time there.
