This paper was presented at the 2023 ASME Turbo Expo and explores a novel design and optimisation strategy coupling the 3D inverse approach and DoE
(design of experiment) study that is developed.
CFD analysis confirmed that the redesigned compressor wheel has increased the efficiency over the entire performance map significantly, and the detailed internal flow visualisation shows that the reduction of leaking loss is the main contributor to this improvement.
A complete compressor map is obtained and compared with the baseline. The optimal design has a better efficiency across most part of the map, and the maximum pressure ratio is also slightly improved.
