Improving the dynamic performance of continuous-flow mixing of pseudoplastic fluids possessing yield stress using Maxblend impeller

Computational fluid dynamic studies of mixers for highly viscous shear thinning fluids and PIV validation

“…Other common configurations for mixing of highly viscous non-Newtonian fluids are two coaxial impellers, a central one, such as the Scabba impeller or the Rushton turbine, and an external one, such as an anchor impeller. The Scabba impeller and the Rushton turbine have similar constants: 10.5 (Pakzad et al, 2013b) and 9.6-11.5 (Cortada-Garcia et al, 2017, Patel et al, 2012, respectively. In contrast, anchor impellers have larger constants of around 23 (Pakzad et al, 2013a).…”

Hydrodynamic factors in an anaerobic digester

“…Best performance was noted in anchor impeller with biogas production of 22.6 NL/L, and methane content of 84.4 v/v% [12]. A stronger tangential flow is generated by Anchor impeller as compared to other impellers which makes it suitable for mixing viscous fluids [13].…”

“…Maxblend impellers have been found to consume three to four times less power than A320 and Scaba 6SRGT impellers and thus are able to drastically improve the performance of continuous-flow mixing with huge power savings (Patel et al, 2012). Double-helical ribbon impellers running at a moderate speed are usually suitable, although they are not very effective at micromixing, which is essential for fast cell growth and substrate conversion.…”
