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 numerical vortex generator is used to simulate the flow control of double S-type inlet instead of the real vortex generator blade. Based on the experimental design theory, the calculation results of 27 vortex generators applied to the inlet flow control are analyzed, and the parameters of the control device And the different effects of the change on the total pressure recovery and the flow field distortion of the inlet, the optimal parameter combination is given by the response surface method to provide technical reference for the parameter optimization of the passive flow control device with double S-shaped inlet.
