Abstract EN
Variable inlet guide vane (IGV) is used to control the mass flow and generate prewhirl in centrifugal compressors.
The efficient operation of IGV is limited to the range of aerodynamic characteristics of their vane profiles.
In order to find out the best vane profile for IGV regulation, the modern optimization method was adopted to optimize the inlet guide vane profile.
The main methodology idea was to use artificial neural network for continuous fitness evaluation and use genetic algorithm for global optimization.
After optimization, the regulating performance of IGV has improved significantly, the prewhirl ability has been enhanced greatly, and the pressure loss has been reduced.
The mass flow and power of compressor reduced by using the optimized guide vane at large setting angles, and the efficiency increased significantly; the flow field distribution has been improved obviously, since the nonuniform distribution of flow and flow separation phenomenon greatly weakened or even completely disappeared.
The achievement of this research can effectively improve the regulation ability of IGV and the performance of compressor.
