Aymen Laadhari, Pierre Saramito, and Chaouqi Misbah. Vesicle tumbling inhibited by inertia. Physics of Fluids, 24:031901, 2012.   LSM_PhyF_12 Vesicles under flow constitute a model system for the study of red blood cells (RBCs) dynamics and blood rheology. In the blood circulatory system the Reynolds number (at the scale of the RBC) is not always small enough for…

Aymen Laadhari, Pierre Saramito, and Chaouqi Misbah. Improving the mass conservation of the level set method in a finite element context. Comptes Rendus Mathematique, 348(9-10):535–540, 2010.   LSM_CRASP In this work, a new algorithm is proposed for improving the mass conservation of the level set method in the finite element context. Two kinds of Lagrange multipliers are…
