Abstract EN
This paper presents the preliminary steps required for conducting experiments to obtain the optimal operating conditions of a hybrid impeller mixer and to determine the residence time distribution (RTD) using computational fluid dynamics (CFD).
In this paper, impeller speed and clearance parameters are examined.
The hybrid impeller mixer consists of a single Rushton turbine mounted above a single pitched blade turbine (PBT).
Four impeller speeds, 50, 100, 150, and 200 rpm, and four impeller clearances, 25, 50, 75, and 100 mm, were the operation variables used in this study.
CFD was utilized to initially screen the parameter ranges to reduce the number of actual experiments needed.
Afterward, the residence time distribution (RTD) was determined using the respective parameters.
Finally, the Fluent-predicted RTD and the experimentally measured RTD were compared.
The CFD investigations revealed that an impeller speed of 50 rpm and an impeller clearance of 25 mm were not viable for experimental investigations and were thus eliminated from further analyses.
The determination of RTD using a k - ε turbulence model was performed using CFD techniques.
The multiple reference frame (MRF) was implemented and a steady state was initially achieved followed by a transient condition for RTD determination.
