Abstract

The violent oscillation of the bubble formed from the evaporated droplet at the superheat limit has been investigated analytically and numerically. In this study, we have formulated a general bubble dynamics model, which is suitable for the oscillating bubble in an incompressible liquid medium. One of distinct features of this model is that the velocity and temperature distribution of the gas inside the bubble are obtained by solving continuity and energy equations for the gas analytically. With uniform density and temperature distribution approximation, the calculated values of the far field pressure signal from the evolving bubble formed from the fully evaporated droplet are in good agreement with experimental results.
