RESULTS: CASES WHERE DICE AND CFD DIFFER Some cases where DICE gives poor results: Case C05: obstacle omitted. Case A28: flow reversed. Copyright <strong>of</strong> Shell Research Ltd October 2012 20
CASE C05 CFD RESULTS Concentration on 4 planes at 1, 3, 5 and 7 m above ground. CFD results shown by contours, experiment by spheres on same scale. Spheres placed at measurement locations. Copyright <strong>of</strong> Shell Research Ltd October 2012 21
