Goals

Objectives and Integrative Aspects of the Research Program

Primary scientific objective of the Graduate College is to develop models for the description and simulation of fluid-structure interaction phenomena in engineering. Final result will be reduced models for the engineering practice derived from a thorough mechanical and numerical analysis of the coupled fluid-structure system. The reduced models should be able to describe the actual phenomena with a sufficient accuracy and should support parameter analyses of the problems examined.

The models and algorithms used will be verified and validated with reference to experimental results published in literature. Where possible, simple models with case-dependent applicability guidelines will be derived from the more complex models studied initially.

Intermediate goals of the Graduate College are:

  • Comparison and evaluation of different mathematical and mechanical expressions for coupled field problems in the domain of fluid-structure interaction. Evaluation of different approximation levels in the models with respect to their effect on discretization and solution of the constituting equations.
  • Development and application of methods for the simultaneous discretization of both components in fluid-structure interaction problems. Comparison of coupling algorithms for different space and time scales.
  • Development and application of efficient solution methods for coupled fluid-structure systems. Examination of multigrid methods and parallel solution techniques for coupled multi-field problems.
  • Development of reduction methods for the coupled system.
  • Development of engineering models and examination of the phenomenology of specific engineering problems.
  • The research will be interdisciplinary and, as far as practicable, supported by experimental data obtained from other institutions or departments. Theoretical research will be done also to back up current experimental research conducted by other departments in the areas of water and coastal engineering, steel construction, aerospace and wind energy converters. It is thus possible to verify theoretical models and calculations by comparing them to experimental data and realistic in-situ measurements, and to obtain or derive model parameters.

    However, the Graduate College itself will not conduct experimental research.
