Most likely candidate would be OpenFoam.

www.openfoam.org - Linux version; probably the simplest to get working
sourceforge.net/projects/openfoam-extend/ - Files for running under
Windows; you will also need Cygwin

Remember to add in plenty of time to familiarise youself with the program,
especially if you will need to add features such as your object rotating &
being influenced by the flow field. OpenFoam offer support, which may be
useful, but it is not cheap. However, any commercial CFD, with support at
the level you may need for your features, will also not be cheap, and
there is a good chance that your features will migrate to be part of
'standard' OpenFoam in a later release, benefitting us all.
