Francis vane impeller geometry

[FEH22]

Does anyone have a good reference for the geometry of a Francis vane impeller? I've seen information on their performance characteristics. How do you design an impeller to get these characteristics?

See my reply in thread407-12602. This is my third response to this query? How many more threads did you put it in?

There were four or five. Three or four in the pumps forum and one in the Solidworks forum. I posted the thread yesterday and didn't get any replies. Today, I did a search for "Francis Vane" in the pump forum. It came up with four threads. I went and read them. It looked like the people on the threads might be able to help. I added my request to the threads (I think only three). The solidworks forum thread was discovered through a Yahoo search.

This was my first use of this forum. I wasn't quite sure how to use it. I'll try to be more efficient (and patient) next time.

Sorry for any inconveience.
