Slip flow

[MingyueTianya1]

Dear Professor，

I was wondering if you have an example of slip flow？Or where can I learn about slip flow？

Thanks in advance for your guidance.

We do not have an example, but the idea is fairly simple. It can be modeled by imagining that the parabolic velocity profile extends into the wall a bit like below:

Thank you very much for your reply to the problem, which benefit me a lot. And if I want to add a wetting films in the corners, where can I learn that?
