Why do i get different values for non newtonian fluid with the same setup in both situations?

Alberto Lopez May 16, 2014 7:17 PM

I set up a problem with water and got some reasonable value, but once i change the fluid to olive oil, the values become unrealistic. I'm not sure what i'm missing can someone explain why Flow Simulation does this and what needs to be done to fix it?

What is unrealistic?

What is the problem setup? Is it simple enough to hand calc for comparison?

What are you comparing the solution against?

  The non newtonian fluid temperature does not change.
  
  There is no problem in setup. Not simple enough for hand calculations.
  
  Comparing olive oil to what happens with water both done in flow simulation.

    Setup a test case of flow in a pipe, describe what you expect to happen, post a reference for what your expectations are, post the models. Not enough info to help yet.
