Experimental investigation on shock wave diffraction over sharp and curved splitters
Abstract Shock wave diffraction occurs when a normal travelling wave passes through a sudden area expansion. Turbulent, compressible, and vortical are the characterising adjectives that describe the flow features, which are slowly smeared out due to ...
