Study on cavern evolution and performance of three mixers in agitation of yield-pseudoplastic fluids

Songsong Wang et al.

Summary: The hydrodynamic performance of three mixers (SSC, SSO, DSO) in the mixing of yield-pseudoplastic fluids was investigated. Numerical and experimental approaches were used to determine the efficiency of the mixers. The results showed that DSO mixer outperformed the other two mixers in flow pattern, mixing time, and mixing efficiency.

CFD simulation and experimental analysis of solid-liquid mixing characteristics in a stirred tank with a self-similarity impeller

Deyin Gu et al.

Summary: In this study, a self-similarity impeller based on Hibert curves was introduced to intensify the solid-liquid chaotic mixing process. The hydrodynamics of solid-liquid mixing process in a stirred tank with different impellers were investigated through experimental analyses and numerical simulation. The results showed that the self-similarity impeller consumed less power compared with the conventional pitched-blade impeller, improved the largest Lyapunov exponent (LLE) value, and enhanced the solid particle suspension quality and turbulent kinetic energy dissipation rate.

Floating particles mixing characteristics in an eccentric stirred tank coupled with dislocated fractal impellers

Deyin Gu et al.

Summary: The mixing characteristics of floating particle dispersion in an eccentric stirred tank with dislocated fractal impellers were investigated. The results showed that the combination of eccentric agitation and dislocated fractal impeller improved axial circulation efficiency and enhanced particle dispersion homogeneity while reducing the drawdown speed.

Experimental and numerical investigation of the scale-up criterion of solid-viscous fluid mixing in a stirred tank

Daiqi Lin et al.

Summary: This study validates the scale-up criterion for non-Newtonian fluid mixing in stirred tanks through CFD simulation and experimental verification. The effectiveness of the scale-up criterion is proven by comparing kinematic similarity in non-Newtonian systems. The study also discusses the mechanism of flow regime transformation and demonstrates good performance in terms of scale effect of power consumption, particularly for the CMC2.0 solution system.
