Hi everybody.
I would like to model a micro-channel under slip boundary condition, but I don't have any tutorials or videos, moreover I don't know how to check its accuracy. I appreciate it if you could help me. thanks in advance. |

The slip condition in microchannels is not always valid. You have to determine if it is valid for your case or not. And there is hardly ever a full slip in a microchannel. For full slip, you can use free-slip condition available; specify shear stress of 0 at the wall. For partial slip, you have to use expression or UDF and you need to decide whether you want first-order or second-order slip model.
