Hi,
If you are really going to simulate with the volute you will need a mixing plane in that interface. Both patches of the mixing plane will be non-rotating. In fact it is irrelevant if it is...

I am sorry, I explained wrong.
Concerning the connection between volute and wheel you will have two boundary conditions, they will be of type ggi or mixing plane ( whatever it suits you...
