Towards Particle Image Velocimetry Measurements During Shock-Particle Curtain Interactions

摘要

Preliminary particle image velocimetry measurements of the gas phase upstream of an interaction of a Mach 1.44 shock wave with a dense particle curtain have been performed using a conventional low repetition-rate system. These data show that following the reflected shock step change, the upstream velocity increases with time as the flow equilibrates across the curtain. Time-resolved PIV, performed for the first time in a shock tube, was able to capture the transients associated with the shocks as well as boundary growth. Future work will use time-resolved PIV to quantify shock-particle curtain interactions.
