This case simulates Prandtl-Meyer turning. The geometry is
depicted below:

the streamline.

The North boundary is impervious to flow because it is
located along a streamline (the location of which is
calculated from Prandtl-Meyer expansion theory). At the exit,
the pressure is fixed to the constant value that pertains to the
characteristic line along which the exit boundary is prescribed
to run. The last row of cells is very thin compared to the
others to ensure the accuracy of this pressure fixation.
The grid lines of constant I are set to be coincident with
the theoretically-calculated locations of the characteristic
lines. The grid lines of constant J are uniformly spaced, and
hence must correspond to streamlines.
The predicted contours of pressure are very close to the
grid lines of constant I, which demonstrates the ability of
EARTH to calculate accurately Prandtl-Meyer turning.
