Dynamic Characteristics of a Vapor Bubble in a Droplet

This chapter focuses on the comparisons of dynamic behaviors of dropletsDroplet containing the air and the vapor. The fundamental reason for this difference lies in the existences of vapor condensation. Due to the phase transition, the velocity of fluid propagation and the mechanism of its interactions with shock waves may be changed. Based on this, it is of certain significance to investigate the dynamic characteristics of a vapor bubble inside a droplet. In this chapter, a numerical method is adopted to simulate the movement, deformation, collapseCollapse, and other processes of a vapor bubble, and a quantitative analysis is carried out on the local instantaneous pressure released during the collapse.
