[01138] Advances in embedded and Eulerian methods for fluid-structure interaction

  • Session Date & Time : 4C (Aug.24, 13:20-15:00)
  • Type : Proposal of Minisymposium
  • Abstract : This mini-symposium brings together young researchers and experts working on numerical modeling of fluid-structure interaction problems. To avoid the remeshing step involved in ALE method, other approaches based on non-body fitted grids have become more and more attractive. One is the embedded approach where a Lagrangian structure solver interacts with an Eulerian fluid solver to enforce appropriate conditions on the immersed interface. Another one is the fully Eulerian approach where both the fluid and the elastic structure are discretized on the same grid. This mini-symposium welcomes contributions to embedded and fully Eulerian numerical modelling for both compressible and incompressible FSI.

      • Abstract : In this talk we will present a single-phase FE approach for free surface flows, where only the wave-structure interaction is accounted for, in combination with an unfitted floating structure with arbitrary geometry. In this work we propose a monolithic coupling with block preconditioning, ensuring robustness and efficiency of the solution. We will demonstrate the capabilities of the proposed framework with a series of tests for wave-structure interaction problems, assessing accuracy and conservation properties.
    • [03927] FULLY EULERIAN MODELS FOR FLUID-STRUCTURE INTERACTION: APPLICATION TO CAPSULES

      • Abstract : Capsules have an important potential in the fields of biotechnologies but many scientific aspects, related to their modeling and simulation, are still challenging. In this context, eulerian models for fluid-structure interaction are a very promising tool to understand their behavior when interacting with complex geometries. In this talk, we will present a novel numerical tool to analyze complex applications of deformable capsules by introducing a solid bulk within the membrane.
