Shock-wave/boundary layer interaction control using spark-jet and micro-vortex generator (2016)
Presentation / Conference
Fang, J., Yang, G., Yao, Y., Liu, C., & Lu, L. (2016, September). Shock-wave/boundary layer interaction control using spark-jet and micro-vortex generator. Poster presented at UKTC Annual Workshop, Cambridge, UK

We present Large-Eddy Simulation of two control devices: active control by SparkJet and passive control by MVG. It is found that both methods can greatly alleviate the separation. Flowfield analysis shows that the streamwise counter-rotating vortex g... Read More about Shock-wave/boundary layer interaction control using spark-jet and micro-vortex generator.
