Oil properties in setup of CFX

rusted86 · April 30, 2012, 05:06

Hi

i am carrying out CFD analysis on a valve and i would like to use a material of OIL as the fluid body. i have already carried out simulations with water and air, can anyone tell me were i can find the properties of oil (ie density 918kg/m³) in the materials library as at the moment this has me stumped. Any help would be appreciated.
thanks in advance

Hi,

Here can be some thing near to the density you have, I hope it helps.

I am modeling the oil with the density 895, and since I needed some other properties such as Specific heat capacity and thermal expasivity (probably you need also) which I could not find any where for the oil that I am currently modeling I used the data for another oil which I modeled before with the density 872. I think there sould not be a considereble difference (I am not sure).
Cp = 1954 j/kgK
Thermal expansivity = 0.0007 1/K

Oh, your question was a year ago! 2012!
