Abstract

This paper describes an investigation on the behavior of laser induced vapor bubble in cryogenic liquid nitrogen. The bubble is produced by the pulse ruby laser beam focused in the special cryostat. The dynamics of the laser-induced bubble is visualized by high speed photography. The pressure pulse signals from the bubble motion in the liquid nitrogen are measured under equilibrium or nonequilibrium conditions. Furthermore a numerical study is also performed on the dynamics of single spherical bubble in cryogenic liquid under the conditions corresponding to our experiment. Among the results the rapid growth of bubble and its rebounds have been visualized even in near-equilibrium conditions. Calculated results are compared with the experimented data.
