Since I want to simulate the airfoil in a large stall angle,so I hope to use the low Re number turbulence model to resolve the sub layer.Then,how can I set to avoid using the wall function?

You do not want that FOAM set wall functions for your? In that case you should change the type of the boundary to patch.

Isn't it also possible to keep it as a wall and not use a wall function in the 0 time directory?

Try it, if foam Set wall function also you set zeroGradient, change the type. I remember that sth. Like that was mentioned somewhere at openfoam.org site.
