The use of a propeller impeller in industrial applications can be advantageous for a variety of reasons. Propeller agitators, also known as axial flow agitators, are commonly used in many industries due to their ability to efficiently mix and agitate liquids, as well as some types of low to medium viscosity slurries. Here are some of the key uses of propeller impellers in various industries:
Computational Fluid Dynamics (CFD) helps our engineering team study how a propeller impeller moves liquid inside a tank before finalizing agitator speed, impeller diameter, shaft position and baffle arrangement. For axial-flow propeller impellers, CFD visualization is especially useful because the main objective is strong top-to-bottom circulation with minimum dead zones.
At Premix Technologies, CFD analysis supports practical agitator selection for water treatment, chemical processing, food, pharmaceutical, fermentation, blending and low-to-medium viscosity slurry applications. The video below demonstrates how flow lines and velocity distribution can be reviewed to improve mixing efficiency and reduce uneven circulation inside the vessel.
