Аннотация доклада:
High-speed non-stationary gas flow in shock tube has been studied with four panoramic visualization methods (shadowgraphy recording with digital CCD cameras, Particle Image Velocimetry (PIV) method, discharge visualization method and particle tracing). The flow evolution was recorded for 12 ms after shock wave passed with high speed re-cording (digital camera Photron High speed camera Photron FASTCAM SA5, exposition 1-2 µs at recording rate 300-500 frames per second). Digital image processing was used for images and video films – cross-correlation processing with Davis soft, background subtraction, and glow intensity analysis.
