Since I'm not familiar with the Woodward-Colella problem. Do you mean the flow geometry as in the figure below?

You will have the following Boundary Conditions:
SupersonicInlet boundary conditions on the inlet section
ExtrapolatedOutlet boundary conditions on the outlet section
Slip boundary conditions on the top and bottom walls

The slip boundary conditions can be set in the following way.

dUdy = 0 (free-slip)
V = 0 (no penetration)
dpdy = 0 (neumann)

I believe these should provide you with proper results.
