Résumé Français : cf. version anglaise

Résumé Anglais : Flapping flight research is an intrinsically multidisciplinary activity, equally important for biologists and for engineers. The objective of this project is to develop efficient numerical tools for the fluid-structure interaction (FSI) in flapping flight. Earlier studies have demonstrated the usefulness of numerical modelling. Further progress requires constant improvement of computational techniques. One on the major recent areas of research is free flight manoeuvring stability and control, and it is believed that the wings deformation plays a significant role in these processes. It presents new challenges to the numerical modelling in terms of efficiency and accuracy. Therefore, the proposed work focuses on the development of an adaptive method for numerical simulation of animal free flight with flexible wings. The new development will be based on our previous work on a Navier-Stokes solver with volume penalization. While the fluid structure interaction can be simulated using the FSI extended volume penalization method, adaptive grid refinement has yet to be developed in this context. T. Engels, D.
