Large-eddy simulation of a three-dimensional shock-wave/turbulent boundary layer interaction of a single-fin (2015)
Presentation / Conference Contribution

The three-dimension (3D) shock-wave/turbulent boundary layer interaction (SWTBLI) raised from a hypersonic flow passing a single-fin at Mach 5 is investigated i by using LES. The performed LES has demonstrated very good agreements with available expe...
