Basic Study for Crushing of Ice by Underwater Shock Wave


Article Preview

The aim of this study is to confirm a new technique that can crush ice by underwater shock wave generated by underwater explosion of explosive. Damage caused by ice occurs in the cold regions at different circumstances. For example, the problems such as accretion of ice on the drainage of snow melting system, on the ship and on farm lands. The solution for such problems is to use a method of heating. As the necessary quantity of heat is enormous and the problem of global warming exists, the dynamic way of solving is desirable. At first, we carried out experiments using detonating cord and ice block. The process of propagation of shock wave in ice was observed by using the high-speed camera.
