SHEAR RATES ON TURBINE IMPELLER BLADES
Chemical Engineering Communications, 1984Shear rates on the front side of a turbine impeller blade have been measured by an electrochemical method. The values obtained for water, CMC solutions and a kaoline suspension have been found to be in general higher than assumed so far. The data agree (for ReM > 10) satisfactorily with the predictions from the laminar boundary layer solutions for the ...

Effects of impeller trimming influencing pump as turbine
Computers and Fluids, 2012Abstract Pump manufactures normally do not provide performance curves of their pumps working as turbines, especially performance curves of trimmed impellers. Impeller trimming is necessary to adapt to a certain operating condition. Therefore, establishing the correlation of PAT’s performance curve and impeller trims is essential.

New Turbine Impellers for Viscous Mixing
Chemical Engineering & Technology, 2008AbstractNew open impellers developed for viscous mixing applications were characterized experimentally in terms of power consumption and mixing times, and their performance was compared to that of standard turbines. Their design is based on a nonsymmetry of revolution principle contrary to standard impellers.

Mistuning and Damping of Turbine Impellers
MTZ worldwide, 2015Modern combustion engines have to comply with a permanently growing requirement profile with respect to economy, power and environmental acceptability. In this regard, the turbocharging technology became more significant. Primarily, casted radial impellers are deployed in small and medium sized turbochargers with wheel diameters ranging between 30 and ...

Hydraulic characteristics of turbine impeller
Collection of Czechoslovak Chemical Communications, 1982The study concentrates on the determination of hydraulic characteristics (volumetric flow rate, power output, hydraulic efficiency and total head) of a standard, six-blade turbine impeller in a flat-bottomed cylindrical vessel provided with radial baffles at a turbulent regime of agitated liquid. The investigated characteristics are determined by means

Turbine impellers as gas‐liquid contacting devices
Journal of Applied Chemistry, 1963AbstractThe performance of turbine impellers has been investigated by conventional sulphite oxidation technique in a 5‐litre vessel in sparged gas‐liquid and gas‐liquid‐solid systems. Performance may be limited by flooding of the impeller and slipping and by a third effect for which the term ‘overloading’ is proposed.

Hydraulic efficiency of a Rushton turbine impeller
AIP Conference Proceedings, 2017Based on CFD simulations hydraulic efficiency of a standard Rushton turbine impeller in a baffled tank was determined at a Reynolds number of ReM=33330. Instantaneous values of pressure and velocity components were used to draw up the macroscopic balance of the mechanical energy.
