Displaying axial velocity of fluid flow in pipe?

[Anonymous]

Hi,

I'm simulating fluid flow in a helical pipe and would like to plot the axial velocity at several cross sections. At one location, this happens to be the velocity in the x direction (pictured). At every other location in the pipe, it's a combination of the Vx, Vy, and Vz in varying proportions. The only result that can be displayed, however, is Vx, Vy, Vz, or Vmagnitude. Is it possible to display the axial velocity at other locations? 

Cheers

Could you create a custom results quantity from the vector velocities that gives you what you are after?  Just be aware you have to solve the sim first before the scalar variables are available for use in a custom result equation.

This is hard task to do. What about using CAD software to create a pre-cut helical pipe prior running? then post-process would be on transversal planes at least? Or read all white papers on the subject, perhaps you can take some post-processing ideas from other CFD researchers

I may have misunderstood.  Do you want the radial velocity relative to the center axis of the helix or relative to the center axis of each cross section?

Hi Bob,

the radial velocity relative to the centre of each cross section.

funny way to look at a velocity profile in 3D
