Figure 3.4<br />
Figure 3.4 shows the inability of the grid to predict the flow within the first meters above the<br />
ground. Results of the <strong>simul<strong>at</strong>ions</strong> always underpredict experimental d<strong>at</strong>a below 20 meters.<br />
Figures 3.5 to 3.8 show the total velocity <strong>field</strong> for the different <strong>simul<strong>at</strong>ions</strong> with grids a, b, c<br />
and d. Velocities are displayed <strong>at</strong> the first cell row, with contours for the first component of<br />
velocity. These results can not be compared against experimental results but can help towards<br />
further understanding of the different cases.<br />
