A level-set method for bubble growth in acoustic droplet vaporization

초록

A level-set method is presented for computation of bubble growth in acoustic droplet vaporization (ADV) including the interactions between the liquid-vapor interface and the liquid-liquid interface as well as the effects of vapor compressibility and liquid-vapor phase change. The ghostfluid and semi-implicit pressure correction methods are implemented into the level-set method for compressible bubble growth with phase change. The numerical results for several test cases show good agreement with the analytical solutions. The level-set method is applied to investigate the effects of wall and ambient temperature on the droplet and bubble motion in the ADV condition.
