[항공] Stable and Accurate Modeling of Transient Fluid/Structure Interaction

5. 내 용 :
In this presentation, I will summarize recent results obtained in the development of a novel numerical treatment of coupled multi-physics problems, with emphasis on the simulation of transient fluid/structure interaction (FSI) events, such as the propagation of shocks and blast waves along deformable media, flutter instability problems and aeroelasticity-driven failure events in solid propellant rockets.
The talk will focus on two aspects of the on-going research project: (i) the development of an accurate scheme used to transfer fluid-induced loads across non-matching discretized interfaces; and (ii) the formulation and implementation of a new stable and accurate coupling scheme between fluid and solid solvers. Beyond a presentation of the load transfer and coupling schemes, the presentation will summarize the results of a detailed comparative study between the proposed method and existing schemes. This comparative assessment is based on a set of FSI applications of increasing complexity involving flat and curved fluid interfaces. We demonstrate how the new schemes improve the current state of the art in computational aeroelasticity.

Originally from Belgium, Philippe Geubelle got his M.S. and Ph.D. in Aeronautics at Caltech in 1989 and 1993, respectively. After a year as Postdoctoral Research Associate at Harvard, he joined the University of Illinois at Urbana-Champaign (UIUC) in January 1995, where he is currently professor in Aerospace Engineering (AE), with joint appointments in Mechanical Science and Engineering, Civil and Environmental Engineering and at the Beckman Institute. Since 1997, he has been serving on the Science Steering Committee of the DOE-sponsored ASCI Center for the Simulation of Advanced Rockets. He is also serving as Director of the NASA Illinois Space Grant Consortium and as Associated Department Head in charge of the AE Graduate Program.
His research interests pertain to the theoretical and numerical treatment of complex problems in solid mechanics, and, in particular, of quasi-static and dynamic fracture mechanics, functionally graded materials, multi-scale modeling, composite manufacturing processes, failure events in solid propellant rockets and biomimetic autonomic materials. Other research activities involve computational aeroelasticity, structural/acoustic coupling and parallel programming.
