Multiphase CFD investigations of gas–liquid mixing in mechanically agitated reactors, with an emphasis on numerical stability, flow structure, and gas dispersion.
A direct comparison of radial- and axial-flow mixing configurations, with space for velocity, gas-dispersion, and cross-sectional simulation videos.
Flat-bladed disc turbines generate strong radial jets, high local shear, and distinct circulation loops above and below each impeller.
Angled blades drive a strong axial pumping pattern, producing top-to-bottom circulation with lower shear than a Rushton turbine.
A reproducible workflow built around geometry preparation, mesh quality, phase interaction choices, transient convergence, and physically meaningful validation checks.
