First-order spatial and temporal discretization were used. Upwind schemes were used in the spatial discretization. Unsteady 2D simulations were performed using nested Arbitrary Mesh Interfaces (AMI). By 'nested' I mean AMIs within AMIs.
In cyclorotors, the blades have a rotation behavior that depends on its azimuthal location in the rotor. The blades rotate on their own axes within the overall rotation of the rotor. The capability to model this is not available in the standard OpenFOAM utilities, so I wrote a custom utility for this. It can be found on my Github page.
The following are pictures of the mesh used in the validation. The nested rotation zones are apparent from the circular discontinuity boundary around each blade.
