Hydrodynamics in an agitated vessel equipped with turbine impeller with curved blades was analyzed by computational fluid dynamics method. Numerical simulations for a liq. of low viscosity (water) and for gas-liq. system (air-water) agitated in a baffled vessel of inner diameter 0.288 m were performed by using a com. solver. The impeller region was explicitly included by using the multiple ref. frames method, to account for the relative movement between impeller and baffles. The k-epsilon model of turbulence was used for predicting the fluid turbulence flow for the steady-state simulations. The results were presented as axial and radial contours and radial distributions of the fluid velocity as well as kinetic energy of turbulence and its dissipation rate in the agitated vessel.
