Abstract

Though subaquatic explosions have been the subject of many studies, the interaction of the subaquatic shock wave with the liquid air interface is not well known, particularly in its earliest effects. In particulary, microscopic and precocious events occur during the acceleration of the free surface of the liquid. Several techniques (fast camera, image convector, schlieren and ombroscopic records,...) have been used to record the main phenomena in water and surface motion. The free surface motion details have been observed by holographic techniques which appeared very suitable for the description of the first phenomena. We used light sheet for the observation of latter events, plume and its composition.
