Computational treatment of mixing process in stirred tank

Abstract EN

Stirred tanks are widely used in many industrial processes.

the quality of mixing process generated by the impellers can be determined using either experimental and simulation methods by using computational fluid dynamics (CFD) or both methods.

in this study computational fluid dynamics were performed to examine the flow characteristics of six flat blades Rushton turbine type in cases of one impeller only and two impellers in baffled tank, making an optimization design for mixing tank.

the multiple reference frame (MRF) approach was used to simulate the impeller rotation.

ANSYS fluent 15.07 solver and the RNG turbulence model were used.
