Research Abstract

In this research project, we study the light emission mechanism of micro-bubbles by shrinking and collapsing in mercury. In order to evaluate the aggressiveness by cavitation bubble collapsing due to the luminous phenomenon in particular, the luminous phenomenon were experimentally observed. Numerical calculation was carried out for the emission of sonoluminescence bubbles at collapsing.
Experimental results from two types of observation were evaluated at taking account of the sonoluminesence and the triboluminescence.
