Abstract

We consider the effects of the bending rigidity of a capsule membrane convected by Poiseuille flow. We show numerically how the transition from a ``discoidal shape'' to ``V shape or cordial form'' capsules is mediated by travelling waves responsible for the required change in curvature. We show numerically that the wave velocity is an increasing function of both the rigidity of the membrane and the pressure gradient. A qualitative explanation of the observation is given in terms of a Burger's type equation for the curvature.
