title = "High-Speed Imaging of Interaction of Liquid Drops with Hypersonic Projectiles",
abstract = "Water drops were suspended in the flight path of high-speed projectiles fired by the Naval Surface Warfare Center Dahlgren Division{\textquoteright}s (NSWCDD{\textquoteright}s) electromagnetic launcher (EML) located at the Hypersonic Research and Integration for Surface Engagement (HYRISE) facility at the Potomac River Test Range. Drops of diameter 1-3 mm were suspended in place using acoustic levitators and backlit with a pulsed laser synchronized to a high-speed Kirana camera. This enabled aerobreakup study at high Weber number (5e4-4e5), Mach number (1.5-1.9), and Reynolds number (6e4-3e5). We found that non-dimensional drop-diameter increase and drop acceleration were consistent with previous drop breakup studies. Mass shedding and breakup behavior are also consistent with previous drop breakup studies. Drop deformation consistent with what we believe to be Rayleigh-Taylor piercing was observed for certain cases where the instability wavelength was long enough to be captured with the current experimental setup. Drop-remnant/projectile collision was found to result in high-speed radial liquid jetting that appears to drive a shock wave radially from the impact location. Drop-remnant/projectile collision also results in a shock propagating in a direction normal to the projectile surface.",
