Response and recovery times of elastic and viscoelastic capsules in shear flow
Abstract
© Global-Science Press 2015.Amid the recent interest in the role of membrane viscosity
in the deformation of a fluid-filled capsule, we consider the role of various capsule
properties (shear elasticity, membrane bending stiffness and viscosity) in determining
the response and recovery times of a spherical capsule in shear flow. These times
are determined by fitting exponential functions to results for the Taylor deformation
parameter Dxy. We focus on the relationship between the membrane and fluid viscosity
ratios, as suggested by Diaz et al, and whether adjustments to the fluid viscosity
ratio may be used to approximate the effects of membrane viscosity. Based on its ability
to reproduce response and recovery times, our results suggest that such an approach
holds promise.

My research focuses on algorithms for fluid-structure interactions in blood flow,
such as deformable blood cells, circulating tumor cells, and vessel walls.
