Hi, I have a question to simpleSRFFoam. I cannot find a definition of Urel. Relative to what is Urel? And why does simpleSRFFoam use Urel instead of U absolute?
Thanks in advance! |
Hi Miku,
Urel is the relati
Hi Miku,
Urel is the relative velocity in the rotational frame, the absolute velocity would then be: Uabs = Urel + omega x R where omega is the angular velocity vector and R the position vectro in rotational frame. |
Hi Miku,
Maybe you will find

Thanks for your answers!

Thanks for your answers!
If I have not defined a rotational frame and my rotational axis is equivalent to the z-axis of my stationary coordinate system, I am right that my relative velocity is equivalent to my absolute velocity? miku |
Hi Miku,
The relative velocit
Hi Miku,
The relative velocity is identical to the absolute one, when there is no transport velocity (in your case 0 rotation or 0 rpm). Dragos |
