How Agitator Impeller Design Affects Shear and Flow

An Introduction to Shear and Flow. Agitator impellers transmit energy into fluids through shear and flow. Without shear and flow, there would be no mixing, which we refer to as "plug flow.". Your unique process requirements will determine whether the agitator impeller design creates more flow or more shear in your agitator mixer.
