在低速风洞中采用微型叶片作为涡流发生器对某S弯进气道进行流动控制,通过风洞试验研究了微型叶片的不同参数(包括叶片高度、轴向位置、安装组数)对进气道气动特性的影响。试验测量了来流风速V=60m/s、模型攻角α=8°的条件下有/无微型导流叶片时进气道出口截面的总压和静压分布,并由此计算得到进气道出口截面的总压恢复系数和畸变指数。试验结果表明:微型叶片的不同参数(包括叶片高度、轴向位置、安装组数)对进气道流动有明显影响;通过在进气道第一弯道处安装合适高度和组数的微型叶片涡发生器,可以明显改善进气道出口流动;在现有的试验条件下,叶片高度h/Ri=0.02、轴向位置Xvg/Ri=1、组数Nvg=8是相对较优的流动控制方案,主要表现为:与未安装微型叶片相比,进气道流量系数φ=0.8时出口畸变指数降低了0.051,总压恢复系数提高了0.007。 In a low-speed wind tunnel, a micro-vane is used as a vortex generator to control the flow of a S-curved inlet airway. Different parameters of the micro-vane (including blade height, axial position and installation group number) Road aerodynamic characteristics of the impact. The total pressure and static pressure distribution at the outlet of the inlet were measured with / without micro-guide vane at a flow velocity of V = 60 m / s and an angle of attack of α = 8 °. The air inlet pressure The total pressure recovery coefficient and distortion index of the exit cross section. The experimental results show that different parameters (including blade height, axial position and installation number) of micro blade have a significant influence on the flow of the inlet airway. By installing miniature blades of the appropriate height and number at the first curve of the air inlet, Under the existing test conditions, the blade height h / Ri = 0.02, the axial position Xvg / Ri = 1, and the number of groups Nvg = 8 are comparatively superior flow control Program, the main performance is: Compared with the non-installation of micro-blades, outlet flow coefficient φ = 0.8 exit distortion index decreased 0.051, the total pressure recovery coefficient increased 0.007.
