• Resumen

  • A new framework for two-fluid flows using a finite element/level set method is presented and verified through the simulation of the rising of a bubble in a viscous fluid. This model is then enriched to deal with vesicles (which mimic red blood cells� mechanical behavior) by introducing a Lagrange multiplier to constrain the inextensibility of the membrane.

    Moreover, high order polynomial approximation is used to increase the accuracy of the simulations. A validation of this model is finally presented on known behaviors of vesicles under flow such as ��tank treading�� and tumbling motions.
