Fluent vs. CFX vs. Star CD
Does anyone have any opinions on which if these packages is better for the beginner user for modeling centrifugal turbomachinery?

(1). In response to your e-mail, even though I have given you the recommendation about the code which I think is more widely used in pumps and fans, it is still a good idea to visit each vendor's website to get more samples related to your applications. (2).Radial turbomachinery is highly 3-D, and the flow field always involves flow separation even under the design conditions. (3). It is also a good idea to read the ASME/ Journal of Turbomachinery. You should be able to find some published CFD papers related to the radial turbomachinery.(centrifugal pumps and fans)

Sam, I think it is too hard to answer this type of question and I don't think that there is a reliable answer at all. To answer your question you should try to use these codes for solving the same problem and compare its outcome with experimental results.
