Hi folks,

maybe I'm going about this the wrong way or I'm just misunderstanding the model.

But when using a Low Reynolds Model (with no-slip at the wall) I can't find the expression for the friction velocity in the "Equations" section.

Does anyone have any info on this?

The reason why I need to find this expression is so I can modify it a bit for my cases.

Best Regards,

Rui Silva
