Slip and No Slip

What is the difference between slip and no slip options in the boundary conditions of laminar flow. which will be a suitable option to choose for blood flow in capillaries.

Re: Slip and No Slip

The no-slip boundary condition at a wall is always more accurate. You should use for blood flow in capillaries. The slip wall condition is for cases where viscous effects at the wall are negligible...

Re: Slip and No Slip

Hi no-slip is the fact that a fluid velocity tends to "0" at the solid-fluide interface, noslip there is no fluid-surface friction at all. Form most fluid problems, at least in laminar no-slip is...

Yes I was … the overall score is definitely in your favor though Ivar ;)

Re: Slip and No Slip

Hello, on No slip wall u,v=0 and you have boundary layer in slip wall normal velocity is zero but the tangential velocity is not zero (v=0,u is nonzero) and you do not have boundary condition. I have...

Re: Slip and No Slip

i have read the above discussion please tell me how to apply these conditions in comsol 5.0 on SAW device interacting with droplet.

Re: Slip and No Slip

in COMSOL no slip means both u=0 and v=0 for 2D flow, right? What about at two liquid interface? suppose air is flowing over a pool. what boundary condition is appropriate at the interface? I think...

Re: Slip and No Slip

Rajib, In this case, it is usually assumed that the tangential components of velocities in two fluids at the interface are equal. This is a kind of "no-slip" condition since the relative velocity of...
