Streamlines of a fluid moving inside a pipe that is also in motion

      Hello,


      I have a pipe that is being translated in space back and forth with fluid moving inside of it. When I try to visualize the velocity streamlines of the fluid, Fluent shows me streamlines that correspond to the velocity of the pipe, not the fluid inside the pipe. How can I see the streamlines of the fluid with respect to the pipe, even though the velocity vector is dominated by the overall movement of the pipe?


       


      Thanks

      Hi,


      Check out the 'Reference zone' from the 'Reference Values' set-up options (section 32.12.2., Fluent Users Guide). Selecting the desired reference zone will allow you to plot relative quantities. Also go through section 9.3.6. - Postprocessing for MRF and Mixing Plane Problem. Here is a snip.



      I hope this answers your question.


      Best Regards,


      Karthik
