The air flow domain around the impeller has been uploaded in STEP format to the SimScale platform including a specific solid body for the rotating domain around the impeller. The mesh was generated using the hex-dominant mesh operation for internal fluid flow additionally taking care of the rotating domain. The resulting mesh consist of close to 1.9 million cells.
The simulation was set up using the analysis type for steady-state, turbulent flow utilizing a k-Omega-SST turbulence model. Additionally the rotation of the impeller was simulated using a rotating reference zone around the impeller. The simulation results are shown below
The results enable the early visualization of the pressure and velocity field as well as numerical values regarding pressure increase and volume flux. The simulation was carried out on a 32 core machine and took only 20 minutes.
