Investigation of three-dimensional shock wave/turbulent-boundary-layer interaction initiated by a single fin (2016)
Journal Article

Three-dimensional shock wave/turbulent-boundary-layer interaction of a hypersonic flow passing a single fin mounted on a flat plate at a Mach number of five and unit Reynolds number 3.7×10^7 was conducted by a large-eddy simulation approach. The perf... Read More about Investigation of three-dimensional shock wave/turbulent-boundary-layer interaction initiated by a single fin.
