Abstract

A numerical/theoretical analysis is presented to characterize the dynamics of a spherical vapor bubble, collapsing at different degrees of severity quantified by the non-dimensional number, B [1]. Interplay between the momentum and energy dynamics is examined, and it is mathematically shown that the two are connected through the interfacial vapor velocity and the rate of change of vapor pressure. It is shown that for the limiting cases of heat transfer and liquid inertia dominated collapse, the small magnitude of interfacial vapor velocity corresponds to an uncoupled behavior between the energy and momentum dynamics. However, away from these limiting cases, in the intermediate regime, both the energy and momentum are connected due to an appreciable magnitude of interfacial vapor velocity.
