CFD Assisted Impeller Selection
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.
What We Check During CFD Review
Flow pattern, circulation path and tank turnover
Dead zones near tank bottom, corners and wall areas
Impeller tip speed, velocity distribution and turbulence level
Solid suspension behavior for slurry or process tank applications
Baffle requirement to control vortex formation and improve turnover
Power draw and mixing performance before final agitator sizing
Why It Matters for Customers
Better impeller selection for the actual process duty
More uniform blending, suspension and heat transfer
Lower risk of stagnant zones, sedimentation and poor batch quality
Improved confidence during scale-up from pilot to production tanks
Optimized motor, gearbox and shaft design for reliable operation
CFD flow visualization for agitator and impeller mixing performance review.
