Parameters optimization of passive flow control device for a dual S inlet by numerical vortex generator model

采用数值涡流发生器代替真实涡流发生器叶片进行双S型进气道流动控制数值模拟,结合实验设计理论分析了27组涡流发生器应用于进气道流动控制计算结果,从中找出控制装置参数变化对进气道总压恢复、流场畸变的不同影响,应用响应面法给出最佳参数组合,为双S型进气道被动流动控制装置参数优化提供技术参考。

The flow field of a dual S inlet with vortex generators is simulated based on numerical vortex generator model.Five parameters which have effect on total pressure recovery and flow field distortion are considered.By using Design-of-Experiment（DOE） theory,twenty-seven vortex generator configurations installed in the inlet are simulated.Based on analysis and optimization of the results,the best vortex generator configuration is presented.The results of this study can provide technical references for optimization design of parameters of dual S passive control devices.
