This article reports recent experimental results in water column deformation and breakup resulting from shock wave loading. Experiments were conducted in a shock tube whose cross section was reduced from 60 mm × 150 mm to 4 mm × 150 mm by using a cookie cutter. Inside the test section a 6.4-mm diameter water column was created. The shock-wave Mach number was 1.3 at atmospheric air. Double exposure finite-fringe holographic interferometry with a double-path arrangement was used for visualization. Interferograms of the water column breakup process at various stages were collected and compared with previous experiments conducted at the Shock Wave Research Center (SWRC) with different Mach numbers and for various diameters. All the results were displayed universally in nondimensional form. Based on water column deformation, the drag coefficient was evaluated and compared with that of spherical droplets.
