Abstract
Computational fluid dynamics simulations have been used to simulate the flow field within the impeller swept region of a baffled stirred tank. Rushton turbine and flat paddle impeller configurations are investigated using sliding mesh techniques, for which no experimental input is necessary. The results from the CFD simulations show reasonable agreement with experimental data for the location of important flow structures close to the impeller blades, including the position of flow recirculation and axis of trailing vortex pairs generated within the wake at the rear of each blade, and the angle-resolved periodicity of the flow field between successive impeller blades.
