Abstract

Equations resembling the Rayleigh-Plesset and Keller-Miksis equations are frequently used to
model bubble dynamics in confined spaces, using the standard inertial term RR+3R2=2, where R
is the bubble radius. This practice has been widely assumed to be defensible if the bubble is much
smaller than the radius of the confining vessel. This paper questions this assumption, and provides a
simple rigid wall model for worst-case quantification of the effect on the inertial term of the specific
confinement geometry. The relevance to a range of scenarios (including bubbles confined in microfluidic
devices; or contained in test chambers for insonification or imaging; or in blood vessels) is
discussed.
