I had to calculate parameters of the technical oil flow in Ansys CFX.
To solve this problem, I used "the Turpentine" (from Standard Ansys CFX material library) as the working body.
Is it right ?
I know the actual density of the oil. The Turpentine has similar density. Is it enough to use"the Turpentine" as working body?
Dear Valdimir,
The question need to be asked is what simulation you want to perform.
Is it the flow field simulation with or without the heat the transfer.
However, in Ansys CFX their is option to define your own material properties.
Syed Mughees Ali , big thanks for your reply. I think for my task i may adopting the temperature of the oil without change.
You can take any material from the CFX material library as a template. Than you can open the material properties tab and check whether the physical and thermodynamical properties fit with your intentions and your real working fluid. Furthermore a good idea than to rename the material to what you are really using, not to get confused.

Thomas Frank , thank you very much for your reply.I did it , I checked that density of the turpentine the same. But is it enough ?
Dear Vladimir Dorofeev,
As you are keeping the temp. same you conservation properties will be only mass and momentum. Introduce a new material CFX material library. The two properties you need to worry about is density and second one is viscosity. Keep these properties same as technical oil and you are good to go.
My suggestion to solve the problem.
As you are only concerned about the flow field simulation what you can do is to find a Reynolds number of your flow. Now by applying dynamic similarity you can use any fluid for flow visualization.
