Notes:
The role of membrane surface viscosity is investigated in the transient response of an axisymmetric capsule following a sudden start of external flow. Results obtained in a recent study for capsules with a hyperelastic membrane [Phys. Fluids 12, 948 (2000)] are extended to account for membrane viscosity. The common feature between hyperelastic and viscoelastic membranes is the time evolution of capsule deformation which can be fitted to an exponential function and thus characterized with only two parameters, the deformation at steady state D∞ and the response time τs. Membrane and bulk viscosity have quasilinear and independent effects on the transient response. © 2001 American Institute of Physics.
