| Abstract: | Firstly the simulated annealing algorithm was developed and validated by a multimodal function.Then an effective global optimization strategy was presented,combined with design of experiment,3-D flow field solver and a second-order polynomial response surface models(RSM).This optimization method was applied to aerodynamic redesign of transonic compressor rotor.The object is adiabatic efficiency.The optimized rotor increased adiabatic efficiency by 1.58% and has fine off-design performance.The results showed that the optimization method is time-saving and fine capability. |
