Hi,

I would like to enter pyhsical properties in material section of FLUENT.

I have accepted constant values for density and thermal conductivity. But dynamic viscosity is something different.

How can I enter that attached equation in FLUENT,

that answer is UDF? if it is, how can I upload it? from excel list or something else?

Kind Regards,

Hi,
you can inter this equation by using create /edit materials in liquid proprieties viscosity edit instead of put constant value
i think

First of all thank you for your help,

I just tried some limit temperature values (lower and upper) and I found some results numerically. Then I checked all results how they acted ( linearly going up or down). Then I choosed polynomial-lineer and I entered all viscosity values according to about 15 quantity temperautes values

Kind Regards,
