The CAD model of both the rotating zone as well as the propeller was uploaded in STEP format.
The mesh was generated using the manual hex-dominant mesh operation. The important part is the assignment of a separate cell zone to the rotating region to account for the rotation.
The simulation was set up using a transient, turbulent, incompressible flow analysis type. A k-Omega-SST turbulence model has been used to account for the turbulent effects in the flow field. The analysis was carried out on a 32-core machine where 2 seconds of real time have been simulated. The results allow to study in detail the performance of the propeller.
