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