Using different optical diagnostic methods, namely interferometric holography and shadowgraphy, and utilizing a piezoelectric transducer for precise velocity determination, the laws of reflection and transmission of laser-driven shock waves through an obstacle in water are studied. Experimental results on the velocity of transmitted and reflected shock waves from different materials are reported.
The process of Mach wave generation in air is studied in both plane and spherical geometries. The experimental results reported here are theoretically interpreted using the predictions of a self-similar model of strong explosion along with the hydrodynamic equations of a perfect gas, and a good agreement is found.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
