Abstract
This paper describes deformation, collapse and interaction of two tandem liquid columns exposed to a shock wave and shock-induced high-speed airflow. Experiments are conducted in a shock tube for incident shock Mach number 1.47 in air. Shattering processes of two tandem water columns set in the airflow direction are observed using holographic interferometry. The shattering process is characterized by three stages ; however, the shattering mechanism is different in the last stage. Time variations of longitudinal and transverse diameters, and mass of the two shattering water columns are measured from the interferograms. Experimental results are compared with results for a single water column. It is revealed that a strong interference exists between the two tandem water columns.
