Turbine agitators, also known as radial flow impellers, are a common type of impeller used in various industrial mixing applications. They are characterized by their multiple flat blades extending radially from a central hub. Here are some key features of turbine impellers:
Overall, turbine impellers offer a balanced combination of flow characteristics, moderate shear, and versatility, making them a popular choice for various mixing applications across different industries. However, the specific suitability of a turbine impeller for a given process depends on the fluid properties, process objectives, and vessel geometry, which should be carefully evaluated during the agitator selection process.
Turbine agitators, also known as radial flow agitators, are widely used in various industries for their specific advantages in certain applications. The design of turbine impellers allows them to generate radial flow patterns, which can be beneficial in achieving certain mixing objectives. Here are some of the key uses of turbine impellers in different industries:
It's essential to consider the specific mixing requirements, fluid properties, and vessel geometry when selecting an agitator type for an industrial process. While turbine impellers excel in certain applications, other impeller types may be more suitable for different processes. Additionally, the scale and design of the agitator should be tailored to match the unique needs of each industrial application.
Computational Fluid Dynamics (CFD) helps our engineering team study how the impeller moves liquid inside a tank before finalizing agitator speed, impeller diameter, shaft position and baffle arrangement. For industrial impellers, CFD visualization is useful for reviewing circulation, velocity distribution, turbulence level and possible dead zones.
At Premix Technologies, CFD review supports practical agitator and impeller selection for blending, solid suspension, heat transfer, gas dispersion, slurry handling and process mixing 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.
