Experimental and CFD investigation of power consumption in a dual Rushton turbine stirred tank
TL;DR: In this paper, the power consumption of a single phase and a gas-liquid phase system in a fully baffled stirred tank equipped with dual six-blade Rushton turbines was investigated, and empirical correlations were derived which present new relations in estimation of power consumption and flow regime transitions.

A Mixing Study in a Double-Rushton Stirred Tank
TL;DR: In this article, a simulation of a fully baffled vessel with two six-blade Rushton turbines was used to investigate the flow field, power and mixing time in a stirred vessel.
A mixing study in a double-Rushton stirred tank
TL;DR: Comparisons indicate the potential usefulness of this CFD approach as a computational tool for designing stirred reactors and a considerable reduction in mixing time was achieved and stirring power input was increased by increasing the impeller speed.

CFD simulation and PIV measurement of the flow field generated by modified pitched blade turbine impellers
TL;DR: In this paper, the hydrodynamics generated by modified pitched blade turbine (m-PBT) impellers with down-pumping mode were systematically investigated through particle image velocimetry (PIV) measurements and computational fluid dynamics simulations.

On the fluid dynamics of a laboratory scale single-use stirred bioreactor
Akinlolu Oyekunle Oluseun Odeleye,D.T.J. Marsh,Matthew D. Osborne,Gary J. Lye,Martina Micheletti +4 more
TL;DR: The study shows promise in the use of PIV to improve understanding of the hydrod dynamic environment within individual SUBs and allows identification of the critical hydrodynamic parameters under the different flow regimes for compatibility and scalability across the range of bioreactor platforms.

Laser-Doppler measurements of turbulent-flow parameters in a stirred mixer
H. Wu,G.K. Patterson +1 more
TL;DR: In this paper, the authors measured turbulence parameters in a baffled, Rushton turbine agitated vessel with a laser-Doppler velocimeter, and the necessary corrections for the periodic, nondissipative velocity fluctuations in the near impeller region were made by an autocorrelation method.
Journal ArticleDOI
An experimental study of the steady and unsteady flow characteristics of stirred reactors
TL;DR: In this article, a baffled stirred reactor vessel driven by a six-blade disk impeller was investigated using laser-slit photography, and the results showed an inclination of the impeller stream and the formation of ring vortices above and below, which depend on the clearance.

PIV study of small‐scale flow structure around a Rushton turbine
Kendra V. Sharp,Ronald J. Adrian +1 more
TL;DR: In this paper, the structure of turbulent motions was measured in a region surrounding the blade tips of a Rushton turbine mixer and the tip vortices responsible for micromixing were created in this region.

Mean velocity field relative to a Rushton turbine blade
TL;DR: In this article, the 3D flow field relative to a rotating Rushton turbine blade is acquired for fully turbulent tank conditions by synchronizing LDA measurements with the output of a shaft-mounted encoder.
