2 Interface Location in Single Phase Stirred Tanks

Authors: M. H. Sedaghat, A. Zamani, R. Janamiri, M. Safdari, I. Mahdavi, A. Sinkakarimi, M. Karimi, A. Hoseini

Abstract:

In this work, study the location of interface in a stirred vessel with Rushton impeller by computational fluid dynamic was presented. To modeling rotating the impeller, sliding mesh (SM) technique was used and standard k-ε model was selected for turbulence closure. Mean tangential, radial and axial velocities and also turbulent kinetic energy (k) and turbulent dissipation rate (ε) in various points of tank was investigated. Results show sensitivity of system to location of interface and radius of 7 to 10cm for interface in the vessel with existence characteristics cause to increase the accuracy of simulation.
