FIGURE 10.18 Comparison of simulated and experimental results for pitched blade turbine (normalized axial velocity, Uaxial/Utip). r/T = (a) 0.118; (b) 0.171; (c) 0.197. Traces; simulation results; • Schafer et al. (1998) data (from Ranade et al., 2001a).

The computational snapshot approach was used to simulate flow generated in these three impeller configurations (for more details, see Deshpande and Ranade, 2001). The predicted velocity vectors in the r-z plane located midway between the two baffles for parallel, merging and diverging flow configurations are shown in
