Dynamic viscosity in CFX, realistic values?
 

Hello people,

I am an engineering student and have not worked so much with Ansys and CFX so far (or CFD in general), but my university uses it, so I need your help.

My prof. wants me to simulate the flow of 3 different fluids in a simple geometry. I can choose the fluids on my own, but they have to be

- newtonian (I will take just water)
- dilantant
- shear-thinning

The problem is, that I don't know example values to configure 2 and 3 in CFX and I want to use values that are realistic.

Can someone provide me 2 example fluids and the data for (and) viscosity model that I have to chose in CFX?

Thank you for your help!

Not to sound pedantic, but either your professor forgot to give you the information, or purposely decided not to so you visit the library or search the internet in order that you find what fluids fall on such categories.

My advice is that you search for the models provided by ANSYS CFX (or any other CFD software), you will find what industries require them and typical values for specific fluids.

Once you finish your task, you will not only learn how to use ANSYS CFX for such modeling task, but also accumulate new useful knowledge on fluid mechanics.

Good luck..

Of course I tried to find it on my own with google before, because that normally is easier than registering in a forum and waiting for somebody to help you.:confused:

As I think the main part of my work is not spending hours on finding values, I thought someone could at least show me how to find them.

And to be safe from moralisers, next time I will not mention, that it is for a university homework. ;)
