LSMS is happy to invite you to a Conférence to be held by Pr. Philippe H. Geubell, Department of Aerospace Engineering, University of Illinois. Coupling Schemes for Transient Fluid/Structure Interaction Simulation. March 17, 2011, Room GC C3 30 at 12:15
This presentation summarizes the development of a novel numerical treatment of coupled multiphysics 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, structural-acoustic coupling, flutter instability problems and aeroelasticity-driven failure events in solid propellant rockets.
The talk will focus primarily on the development of an accurate scheme used to transfer fluid-induced loads across non-matching discretized interfaces and its impact on the accuracy of the coupled solution. We will present the results of a detailed comparative study between the proposed method and existing load transfer schemes. This comparative assessment is based on a set of FSI applications of increasing complexity involving flat and curved fluid interfaces. The last part of the presentation will focus on the on-going modeling activities in the area of structural/acoustic coupling.
