Direct numerical simulation of supersonic turbulent flow in an expansion-compression corner at mach=2.9 (2014)
Presentation / Conference Contribution

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 Contribution

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.

Direct numerical simulation of a turbulent flow over an axisymmetric hill (2014)
Journal Article

Direct numerical simulation (DNS) of a turbulent flow over an axisymmetric hill has been carried out to study the three-dimensional flow separation and reattachment that occur on the lee-side of the geometry. The flow Reynolds number is Re H=6500, ba... Read More about Direct numerical simulation of a turbulent flow over an axisymmetric hill.
