摘要
开发了模拟退火算法与响应面方法相结合的具有全局寻优能力的优化程序,采用三维粘性流场求解程序进行流场求解,并对某型轴流压气机转子叶片进行了弯掠数值优化设计。结果表明,弯掠联合采用可以有效地改善流场内的流动状况,减少激波损失与尾迹损失,提高效率,表明了所用优化方法的可行性。
An optimization program with global optimization ability has been developed, which combines simulated annealing algorithm with response surface models. A solution of the flow field is being found by using the three dimensional viscous flow equations. The sweep and twist of a certain type of axial compressor blade are then optimally designed by numerical calculation. Results show that flowing conditions in the flow field can be improved effectively by combined sweep and twist, increasing the efficiency by reducing losses caused by shock waves and wakes. This optimization design method is feasible. Figs 6, table 1 and refs 6.
