| Abstract: |
Experimental visualization of non-stationary gas flow with local areas of supersonic flow was conducted by means of Background Oriented Schlieren (BOS) technique. We have acquired images of sequential stages of complex shock-induced flow that originates when a propagating shock wave emerges from the channel of the shock tube of rectangular cross-section. Obtained BOS shift fields allowed to analyze structural features of the flow. Also, a 3D fluid dynamics simulation (CFD) was carried out, based on the Euler system. Results demonstrate qualitative agreement of calculated and visualized images of the flow. Matching data includes time-resolved positions of specific flow elements, such as the front of a shock wave with Mach number 1.5, and dynamics of toroidal vertical structure. |
