Figure

Figure 5.18 shows that if the correlation between resolved and filtered contribution de- de-creases significantly as the filter size increase and reaches 0 .5 for ∆ f /∆ ref = 10 for both
Figure 6.2 shows the dependence of the subgrid velocity, ˜ α p V d,i (p) , on the resolved slip
Figure 6.3 shows the profiles of average in time appear independent of the heights. Hence, the profiles averaged over two sectional plans will be presented to study the behaviour of the flows
Figure 6.14 illustrates that most of the solid volume fractions tend to decrease as the density increases, which is in good agreement with the observation about the solid volume fraction profiles.
