How to plot radial velocity in CFX 12.1
 
Can anyone tell me how to plot radial velocity in CFX Post? Thank you
I can find the 'rotation velocity' in CFX Post, but don't know how to plot radial velocity

- Head to the 'Turbo' tab in CFD-Post. It'll ask you if you want to auto-initialize everything. If you're running a turbomachinery simulation, do it; it not, skip it.
- Set your axis of revolution.
- Click 'Calculate Velocity Components'.

You now have a 'Velocity Radial' variable in Post. Plot it anyway you wish.

Oh, Thank you very much! I got it

Hello,

When calculating the radial velocity in the exit section of centrifugal impeller using the equation Q/A i found it very differ from its numerical value

Can any one tell me why ?

Thanks

How are you calculating Q, A and the numerical value?

Also, how different?

How to plot radial velocity in CFX 12.1
 
Q is the operating condition i choose and A i calculate it using the impeller diameter D and impeller width b
And the two method is totally different
