Nonspherically symmetric equilibrium bubbles in a steadily rotating incompressible fluid
Chen-Chih Lai, Michael I. Weinstein
This note presents two nontrivial, rotational equilibrium solutions to the spatial uniform gas pressure (isobaric) approximate model of Prosperetti in the inviscid case. Building o…

Asymmetric deformations of a perturbed spherical bubble in an incompressible fluid
Chen-Chih Lai, Michael I. Weinstein
We study the dynamics of a gas bubble in a fluid with surface tension, initially near a spherical equilibrium. While there are many studies and applications of radial bubble dynami…
