     the hydrodynamics generated by the straight version of the maxblend® impeller with newtonian fluids in a baffled stirred vessel under the transitional and turbulent regime has been experimentally characterized by means of the particle image velocimetry technique. the flow fields obtained with the maxblend were compared with those obtained with a double stage classical pitched blade turbine (pbt) and a double ekato intermig® impellers under the same specific power draw. it is shown that these open impellers induce complex local flows in the radial and axial direction, with an intensity decreasing away from the blades. by contrast, the maxblend impeller generates a more regular circulation pattern, with efficient top-to-bottom pumping.
