partialSlipt to moving wal in interFoam

ashokmoravaneni · September 4, 2017, 09:00

Hi all,

I wanted to apply partialSlip BC to moving wall. Can any one please let me know how to assign partialSlip BC to a moving wall. I have done it like follows,

type partialSlip;
value uniform (0 -0.5 0);
valueFraction 0.4;

Here the problem is the wall to which I assigned 0.5m/s velocity is not taking the velocity.
Your suggestion will be greatly appreciated

Thank you.

Hi,

What do you precisely mean by "not taking the value"?

What partial slip b.c. does is that, instead of having no-slip (where velocity vector has a magnitude of 0m/s on the wall) you can prescribe the velocity to be 0.5m/s (x,y,z) on the wall boundary.

I am not sure if you meant that the wall is not moving (which makes sense) or the cell face wall velocity is not 0.5m/s

Hi ,
Thanks for your Response. Actually the wall is moving with a velocity of 0.5m/s. But at the same time I wanna apply partial slip to wall if possible. So I am looking for a BC which facilitates both movingwallVelocity and partialslip.

"Not taking velocity" means, the wall is not moving if I specify
type partialSlip;
value uniform (0 0.5 0);
valueFraction 0.4;

Thank you once again.
