Dynamics of nearly spherical vesicles in an external flow.
Tank-treading, tumbling, and trembling are different types of the vesicle behavior in an external flow. We derive a dynamical equation enabling us to establish a state of nearly spherical vesicles. For a 2D external flow, the character of the vesicle dynamics is determined by two dimensionless parameters, depending on the vesicle excess area, fluid viscosities, membrane viscosity and bending mo...
متن کاملNearly spherical vesicles in an external flow
We theoretically analyze a vesicle with small excess area, which is immersed in an external flow. A dynamical equation for the vesicle evolution is obtained by solving the Stokes equation with suitable boundary conditions imposed on the membrane. The equation has solutions corresponding to different types of motion, such as tank-treading, tumbling and trembling. A phase diagram reflecting the r...
متن کاملDynamics of shape fluctuations of quasi-spherical vesicles revisited.
In this paper, the dynamics of spontaneous shape fluctuations of a single, giant quasi-spherical vesicle formed from a single lipid species is revisited theoretically. A coherent physical theory for the dynamics is developed based on a number of fundamental principles and considerations, and a systematic formulation of the theory is also established. From the systematic theoretical formulation,...
متن کاملFluid membranes in hydrodynamic flow fields: Formalism and an application to fluctuating quasi-spherical vesicles in shear flow
The dynamics of a single fluid bilayer membrane in an external hydrodynamic flow field is considered. The deterministic equation of motion for the configuration is derived taking into account both viscous dissipation in the surrounding liquid and local incompressibility of the membrane. For quasispherical vesicles in shear flow, thermal fluctuations can be incorporated in a Langevin-type equati...
متن کاملTopological instabilities of spherical vesicles.
Within the framework of the Helfrich elastic theory of membranes and of differential geometry, we study the relative stability of spherical vesicles and double bubbles. We find that not only temperature but also magnetic fields can induce topological transformations between spherical vesicles and double bubbles and provide a phase diagram for the equilibrium shapes.
