Multi-objective design optimization for aerodynamic performance of centrifugal compressor impeller
Year: 2024
Type: conference-paper
Abstract: Enhancing the performance of the centrifugal compressor system by optimizing the geometric parameters of the impeller is essential for achieving high thermodynamic efficiency and reducing energy costs. This study proposes a multi-objective optimization design approach to improve the pressure ratio and efficiency of centrifugal compressor impellers. The method combines the advantage of numerical simulation with the response surface method so that a reduction of design effort can be achieved. The Krain impeller is used to validate the optimization platform. The benefit of the developed approach is two-fold. On the one hand, the optimized design increased the pressure ratio significantly to the initial design under different working conditions. On the other hand, the impeller approach offers a reference for designers to optimize the design better. The outcomes demonstrate the viability of the approach, and the integrated optimization platform is reliable.
