Evolution of an elastic capsule in two-dimensional Stokes flow

Michael Higley


Dept. Mathematical Sciences, NJIT



We consider an inviscid bubble surrounded by an elastic membrane. In planar Stokes flow, the deformation of the capsule can be described by adapting existing conformal mapping techniques. We present analytical and numerical results for the evolution and steady states of the capsule. These include the effects of different far-field conditions in the flow, resulting in behaviors such as tank-treading and cusp formation.
