However, since the model will be mapping and transferring pressures to the structural model, the computational model for FSI simulation used a 360° full-blade compressor domain. Fig. 6 presents the boundary conditions of the impeller for structural analysis. The rotating speed applied to the impeller, and the fixed condition was specified to the hole. The temperature and pressure distribution from CFD results were imposed to the impeller surface. In the back plate behind at the impeller, the temperature and pressure condition at the impeller inlet were applied around the balancing hole.The temperature and pressure condition at the impeller exit were specified at the remaining part of the impeller.
