Different modifications of the Rushton turbine were studied in a dual-impeller agitated tank (T=0.4 m), to find the effect of blade form on power draw, turbulent dispersion, gas handling
capacity, mixing, gas holdup, and mass-transfer rate performance under turbulent agitation in
an air-water system. Blade streamlining was found to lead to a lower ungassed power number,
a higher gas flow number before flooding, and increased insensitivity of impeller power dissipation
to the gassing rate.

The performance of any device in which a kinetic process occurs e.g. disinfection, coagulation and chemical reactions is dependent on the mixing regime for a given set of operating conditions. Subsequently by characterising the mixing regime within a device and conducting batch reactor experiments to obtain specific kinetic process parameters it is possible to determine the system’s efficiency. 9th International Conference on Urban Drainage, Por...

Anal. Chem. 2001, 73, 5822-5832 We have developed an electrokinetic process to rapidly stir micro- and nanoliter volume solutions for microfluidic bioanalytical applications. We rapidly stir microflow streams by initiating a flow instability, which we have observed in sinusoidally oscillating, electroosmotic channel flows. As the effect occurs within an oscillating electroosmotic flow, we refer to it here as an electrokinetic instability (EKI)....

This paper presents details of a new test reaction system suitable for sparged aqueous systems at temperatures up to 100oC. This system, which is easy to use, provides the basis for experiments carried out in a standard semi-batch stirred tank reactor agitated with a Chemineer CD-6 hollow-blade impeller. The quantitative characterisation provided by liquid micromixing sheds light on the effect of temperature, and hence vapour pressure, in the ope...
