Abstract : Fluid simulation is a classical problem in numerical analysis and scientific computing. Nowadays it holds a significant place in the computer graphics domain. Those kind of applications are eager of efficient and reliable techniques. My works focus on the development of Lagrangian-Eulerian hybrid methods in a vortex formulation which give good precision and know efficient computation algorithms. Those methods are flexible enough to allow to compute multi-phasic flows as well as fluid-structure interactions. Interfaces between various phases (fluids or solids) are captured by a level set function. I propose a novel method that offers to easily integrate interactions with rigid solids (thanks to a a penalization technique) and deal with collisions. The numerical resultats computed are compared to test cases from the litterature and I offer examples of realistic 3D animations for computer graphics.
