Figure 3.11 : grids e and f show slight discrepancies with experimental results downwind the
top, but fail in predicting downwind the top flow. Grid g gives good results, with remarkable
accuracy for the maximum speed up and velocities on the lee side.
Figure 3.12 : grids e and f give quite good results all the line long, except for the velocity drop
upwind the hill. Grid g captures this drop but yields too low velocities everywhere else along
the line.
Figure 3.13 : grid g provides the best results, but there is no significant difference between the
three tested grids.
