Effects of micro blowing/suction flow control devices on a NACA0015 airfoil (2014)
Presentation / Conference
a NACA0015 airfoil. Paper presented at The 8th International Conference on Computational Fluid Dynamics (ICCFD8), Chengdu, China

As a newly emerged active flow control technique, micro blowing/suction has shown a great potential in reducing the skin friction of turbulent flows. Throughout comprehensive analyses of active flow control of micro blowing/suction devices for a NACA... Read More about Effects of micro blowing/suction flow control devices on a NACA0015 airfoil.

Direct numerical simulation of supersonic turbulent flow in an expansion-compression corner at mach=2.9 (2014)
Presentation / Conference
Fang, J., Yao, Y., Lu, L., & Zheltovodov, A. A. (2014, June). Direct numerical simulation of supersonic turbulent flow in an expansion-compression corner at mach=2.9. Paper presented at ICMAR 2014, Novosibirsk, Russia

Shock-wave/turbulent boundary layer interactions (SWTBLI) are prevalent phenomena in high-speed flights, which could cause large flow separation and high wall heat flux and strong pressure fluctuation, therefore, affect significantly the aero-thermod...

Numerical simulations of two-dimensional and three-dimensional shock wave/turbulent boundary layer interactions (2014)
Presentation / Conference
Fang, J., Yao, Y., Zheltovodov, A. A., & Lu, L. (2014, June). Numerical simulations of two-dimensional and three-dimensional shock wave/turbulent boundary layer interactions. Paper presented at ICMAR 2014, Novosibirsk, Russia

The impinging shock-wave/flat-plate boundary layer interaction is a standard CFD case for two-dimensional (2D) SWTBLI, which represents the simplest SWTBLI configuration for the validation of turbulence models and computational methods. Although plen... Read More about Numerical simulations of two-dimensional and three-dimensional shock wave/turbulent boundary layer interactions.
