Chrispell, J, R Cortez, Damir B Khismatullin, and L Fauci. 2009. “The Dynamics of Immersed Boundaries in Viscoelastic Fluids”. 62nd Annual Meeting of the APS Division of Fluid Dynamics, November 22-24, 2009 — Minneapolis, Minnesota.
Abstract
Many biological fluids are viscoelastic and require a nonlinear constitutive equation to describe the evolution of the extra-stress tensor. We use an immersed boundary framework to model processes that involve the movement of immersed elastic boundaries interacting with a surrounding viscoelastic fluid. We present recent results on applications including dynamics of a closed membrane moving under surface tension, and phase-locking of swimming sheets.
