Equations of Bubble Dynamics

This chapter focuses on the dynamics equations of the bubbles with different types. Firstly, the Rayleigh-Plesset equation for a spherical bubble is constructed and the effects of the liquid compressibilityCompressibility on the equation results are further considered. On this basis, the differences between the equations with different precisions are analyzed. Secondly, three typical cylindrical equations of bubble dynamics are derived respectively. The differences and connections between these equations in form are discussed. Finally, the dynamics equations of the bubble inside a spherical dropletDroplet are established in detail.
