    Abstract
  • An experimental investigation on gas interfacial instability was carried out with particle image velocimetry (PIV) technique. The evolution images and two dimensional velocity field of a shock-accelerated heavy gas cylinder in air were experimentally measured utilizing glycol fog droplets as tracking particle. The results exhibited the typical characteristics and fine structure of instability flow field, which were consistent with the numerical and experimental results published previously. Therefore, the PIV technique is feasible to measure the gaseous interface evolution process, and also is a advanced and accurate diagnostic technology for gaseous interfacial instability experiment.
