Consider Hydrofoil Impellers for Laminar-Flow Mixing

2022-1-17  Hydrofoil impellers have been used since the 1970s in many mixing applications. They usually have three blades, a low angle of attack (15–25 deg. at the blade tip, to avoid boundary layer separation), and a camber in the blade that causes the chord angle to increase from tip to hub ().They have been used to blend low-viscosity liquids in shear-sensitive

Studies of High Solidity Ratio Hydrofoil Impellers for

These aspects are discussed in relation to existing literature which is still relatively scarce. Finally, the advantages of retrofitting are introduced. Parts 2–4 report on a recent, detailed, fluid dynamic study of the Prochem Maxflo T and Lightnin A315 hydrofoil impellers which extends our knowledge of these important impeller types.

High Solidity Axial Flow Hydrofoil Impellers

The MHS Hydrofoil agitator impeller shares efficiency benefits with the LSV in terms of hydraulic efficiency, low power number, and solid suspension performance when compared to a Pitched Blade Turbine (PBT). However, the wider blades and slightly higher power number compared to the LSV also permit it to operate in low viscosity shear thinning

This is an ultralowshear impeller in which flow is caused by three discharge ports located on the impeller shaft. Rotation of those ports creates a low-differential pressure at the base of the

Types of Agitators, Agitator's Design and Significance

2 天前  Cast agitators have two basic advantages, uniformity of material and hard surface. These have tapering blades, and angle of blade varies from root to tip. This produces maximum axial flow. The diameter of Marine Propeller impeller is 15% to 30% of diameter of tank. These have tip speeds between 300 to 500 meters per minute.

The hydrofoil maintains a more axial pattern and projects farther in both radial and axial directions. With a two-impeller system, the pitched blade turbine creates a staged flow pattern, whereas the hydrofoil creates a single-zone pattern from top to bottom, in a 1:1 batch aspect ratio gemoetry.
