Abstract
The current study presents the effects of a diffracted shock wave interacting with a parallel freestream. The experiments were carried out with diaphragm pressure ratio of P4/P1 = 12, where P 4 and P1 are the driver and driven pressures of the shock tube. Air was used as both the driver and test gas. Freestream velocities of Ufs = 120, 140 and 180 m/s were examined. Particle Image Velocimetry (PIV) was used to quantify the velocity and vorticity fields due to the interaction of unsteady and steady flows. Visualization of the flow features was carried out using the high-speed schlieren photography. The pressure reduction with the highest freestream flow was of 8%, due to the attenuation of the shock/vortex interactions was recorded. Copyright © 2010 by N. Gongora-Orozco, H.
