CFD Modeling of Solid Suspension in a Stirred Tank: Effect of Drag Models and Turbulent Dispersion on Cloud Height

Figure 8

Effect of turbulent dispersion force (TDF). Volume rendered plots with isosurface for (a) single-impeller, 10% (w/w) loading, 400 RPM and (b) dual-impeller, 15% (w/w) loading, 150 RPM. The double-headed arrows marked “EXP” represent the location of experimental observation with arrow thickness representing the observed 8% spread in the experimental data. Gidaspow drag model.
