Modeling and simulation of multi-fluid systems. Applications to blood flows

Abstract : In this work, we develop a framework dedicated to the simulation of multi-fluid systems. We present validations and verifications of these methods on interface capture problems and viscous bubbles simulations.We then show that this framework is well fitted for the simulation of the rigid bodies flow.Next, we extend these methods to the simulation of deformable objects reproducing the behavior of red blood cells: the vesicles. We also validate these simulations.Finally, we apply the previous models to open micro-fluidic problems such as the splitting of a suspension at a bifurcation and the rheology in a confined environment.
