Computational fluid dynamics (CFD) method was applied to the study of flow field in the agitation of glycerin fluid with a Rushton impeller and a pitch 4-bladed turbine.
This paper is concerned with characterization of laminar flow field of a Rushton impeller and a pitch 4-bladed turbine (4PBT) operated respectively in a stirred baffled vessel by numerical simulation using CFD Fluent V6.3® software.
Therefore, original grid cell numbers were employed for simulation of the stirred tank.
The simulations were run using the first-order upwind discretization scheme.
At the end of the simulations, the steady flow field in the entire tank was determined.

Simulation results shown that faster angular acceleration made larger pressure fluctuations.
The mesh contained 113 million elements that had been used to perform the simulation on all models in this paper.

The CFD simulation has been performed by using Fluent6 with the pressure based solver to calculate steady incompressible.
The CFD simulation results indicate that in this process, pressures in the pump showed obvious unsteady, too high transient values could make the impeller damaged, and low pressure bring cavitations.
