Impeller flow pattern

WitrynaHydrofoil impellers are commonly referred to as high efficiency impellers since they are designed to maximize fluid flow and minimize shear rate, and therefore these impellers are popular in a majority of mixer installations. The hydrofoil impeller has 3 or 4 tapering twisted blades, cambered and sometimes provided with rounded leading edges. WitrynaA typical liquid circulation pattern set up by a high-speed radial-flow impeller is shown in Figure 8.7. Liquid is driven radially from the impeller towards the walls of the tank where it divides into two streams, one flowing up to the top of the tank and the other flowing down to the bottom.
