对 S 形进气扩压器中的流动分离及其使用涡流发生器叶片或执行器的控制进行了实验研究，以便生成旨在验证 CFD 湍流模型的数据集。基线和受控数据集包括 S 管道表面和 AIP 中的静态和动态压力测量。第一步，评估了机械涡流发生器的几种配置的效果。在第二步中，获取各种控制幅度、控制频率和雷诺数的主动流量控制数据集。
Flow separation in an S-shaped intake diffuser and its control using vortex generator vanes or actuators were studied experimentally in order to generate a data set aimed at validating CFD turbulence models. The baseline and controlled data sets comprised static and dynamic pressure measurements on the S-duct surface and in the AIP. In a first step, the effects of several configurations of mechanical vortex generators were evaluated. In a second step active flow control data sets were acquired for a variety of control amplitudes, control frequencies and Reynolds numbers.
