Hi Everyone,
I am trying to simulate a water lubricated bearing on CFX. With that in mind, I want to take into consideration the viscosity variation with temperature. The attached photo shows the relation between the kinematic viscosity [cSt] and Temperature [K]. I would like to import this formula into CFX, and I tried writing an expression, but without any success. Can anyone explain to me on how do that please? Note: a, n, and m are constants. Thank you very much in advance! Capture.PNG |
