Improved Body Force Model for Estimating Off-Design Axial Compressor Performance

open access: yesEnergies, 2022
Based on the COMSOL software, body forces substituted into the Reynolds-averaged Navier–Stokes (RANS) equations as the source terms instead of the actual blade rows were improved to better predict the compressor performance. Improvements in parallel body
