Effect of the slip condition on the flow and expected wall-model requirements.

Effect of the slip on the flow	Expected requirements
Mean velocity profile shift depends on slip length	Compute the slip lengths that provide the correct mean velocity profile
RMS velocity profiles insensitive to changes in slip lengths except at the wall	Provide non-zero Reynolds stress at the wall to avoid spurious peaks of the streamwise RMS velocities
Slip boundary condition sensitive to changes in grid resolution and Reynolds number	Robustness to the changes in grid resolution and Reynolds number
