Experiments reveal the self-rotation mechanism during transitions of oblique shock trains in Mach 2.5 flow, suggesting complex asymmetric patterns.
Key Points
The study reveals that the transition from top large separation to bottom large separation in oblique shock trains is influenced by three-dimensional self-rotation.
Experimental findings show the presence of an intermediate mode, side large separation, highlighting the complexity of the three-dimensional structure.
The investigation utilizes schlieren images from multiple angles to analyze the asymmetric patterns of the shock train during transitions.
Understanding these transitions in oblique shock trains at Mach 2.5 is crucial for improving designs in supersonic flow applications.
