Viscous Fluid Displacement by the Growing Bubble

摘要

Equations were derived for the forces experienced by the growing bubble in displacing the liquid radially. The derivation was based on integrating the viscous dissipation function over the entire surface of the bubble. The resulted equations were applicable to bubbles in boiling and in cavitation. The derived equations were validated by applying them to the heterogeneous nucleation and growth of bubbles from cavities in pool boiling and in cavitation. The derived equations approached asymptotically the familiar equation of heterogeneous nucleation and growth of bubbles.
