ABSTRACT: The Computational
Fluid Dynamics (CFD) have been used in the analysis and design of agitated
vessel. Most of the researches done in this area are limited to the baffled or
unbaffled stirred tank. In this paper, we have been interested in studying of
the new design. Particularly, the flow and turbulence fields in square vessel stirred by a standard Rushton turbine have been simulated by
means of CFD techniques. The Navier-Stokes equations governing the phenomenon
of transfer of momentum are solved by a discretization method for finite
volume. The MRF approaches can be used in simulation of the steady state
problem. The numerical results from the application of CFD code Fluent with the
stationary approach Multi Reference Frame (MRF) are presented in the planes
containing the blade. The validation of CFD results with experimental
measurements showed a good agreement.
