Hi all,
can any of you out there give me a tip to find a source regarding propeller calc/design? Will try to manufacture a propeller for a mixer.

They design marine props but they may be able to help

something to start with.

For "large" (12"<D_impeller<120") industrial mixers, simpler geometry such as a 45° pitched blade turbine are often used. They will pump large quantities at lower speeds than a marine prop, and have the benefit of a moderate amount of shear, but at lower efficiency. Running at a lower speed simplifies shaft design and vibration problems. There are also other axial impellers that are called hydrofoils, but are in reality bent plates that very roughly approximate a hydrofoil shape. They are more efficient than a pitched blade turbine, but have lower shear. Depending upon the application, the compromise between high shear with low efficiency and low shear with high efficiency must be made.

I thank you all for your response at my question.
