Htri - fluid shell velocity

[cap_pelela]

Hi, i have been using the HRTI software to simulate a shell and tube exchanger. I dont know which theorical model it uses, so i want to know which is the recommend velocity for the shell fluid.

Please, I appreciate if to someone help me. if i miss a data, let me know. I realy need this informations.

Many thanks

Normally you may use Set your Componenet by component for your mixture, and use Program for Property option. HTRI will then estimate the most mixtures.

I havent got a mixtura. It is all liquid. But how i dont know which formulas the programs uses i dont know which is a appropriate velocity for the liquid of the shell. I hope you can help me.

thank in advance

Just select the component you have - which chemical they are - say water or Benzene. Which component do you have?
Try to open the case file "XIST_Liquid_Liquid_Example.htri" in Samples folder. And look under hot fluid Properties you see a way to do it.
The program will chose itself if the mixed phase is liquid by the pressure and temperature you set.

If you really want to find which method HTRI use to calculate say viscosity you may take a look in the HTRI design manual say from this thread:

If you have "you own" components (unknown by HTRI) you may import from other softwares or enter these in the "Liquid Properties page" for one temperature (then constant) or two temperatures (then interpolated between these). You may look up "Liquid Properties page" in help.

I hope this could help you on the way :-)

Thank u , good iob

PLEASE I NEED HTRI USER GUIDE OR ANY MATERIAL THAT WILL GIVE A STEP BY STEP APPROACH ON HOW TO SIMULATE THE SOFTWARE.it seems that the design manual is more of theory.plllllllllllllllllllllllllsssssssss

You may use the Help and chose the tutorials.. in the help menu of HTRI (step/step entering data). Take a look on the Samples files..
Or take a look in this thread:
