Turbulent Wind Gusts and their Impact on Lightweight Flexible Structures

Principal Investigator: Univ.-Prof. Dr.-Ing. habil. Michael Breuer , Department of Fluid Mechanics, Helmut-Schmidt-University, Hamburg (Germany)

HPC Platform used: SuperMUC of LRZ

Local Project ID: pr53ne

The interaction between fluids and structures (fluid structure interaction/FSI) is a topic of interest in many science fields. In addition to experimental investigations, numerical simulations have become a valuable tool to foresee complex flow phenomena such as vortex shedding, transition and separation or critical stresses in the structure exposed to the flow. In civil engineering, e.g., structures are exposed to strong variations of the wind, particularly wind gusts, and such high loads can ultimately lead to a complete destruction of the structure. Scientists are leveraging HPC technologies in order to model wind gusts and to comprehend their impact on the FSI phenomenon.

Large-Eddy Simulations of Fluid-Structure Interactions Around Thin Flexible Structures

Principal Investigator: Michael Breuer , Department of Fluid Mechanics, Helmut-Schmidt-University, Hamburg (Germany)

HPC Platform used: SuperMUC of LRZ

Local Project ID: pr84na

The interaction between a turbulent flow field and light-weight structural systems is the main topic of the present research project aiming at the development of advanced computational methodologies for this kind of multi-physics problem denoted fluid-structure interaction (FSI). This should allow to predict these complex coupled problems more reliably and to get closer to reality. An original computational methodology based on advanced techniques on the fluid and the structure side has been developed especially for thin flexible structures in turbulent flows.

Fluid-Structure Interaction of Thin Structures in Turbulent Flows

Principal Investigator: Michael Breuer , Department of Fluid Mechanics, Helmut-Schmidt-University, Hamburg (Germany)

HPC Platform used: SuperMUC of LRZ

Local Project ID: pr47me

Fluid-Structure Interaction is a topic of major interest in many engineering fields. The significant growth of the computational capabilities allows solving more complex coupled problems, whereby the physical models get closer to reality. In order to simulate practically relevant light-weight structural systems in turbulent flows, scientists of the Helmut-Schmidt-University in Hamburg developed and implemented an original computational methodology especially for thin flexible structures in turbulent flows.
