Abstract:

The fluid-structure interactions, that means the interaction of some deformable structure with a surrounding or internal fluid flow, belong nowadays to the most important and challenging multi-physics problems which are aimed to treat by numerical simulations. The topic is of fluid-structure interaction plays a dominant role in many fields of engineering. Therefore, a strong need for appropriate numerical simulation tools exists with a variety of numerical and physical aspects. The special task of the present paper is to take care about fluid-structure interaction using modern simulation techniques such as coupled field analysis. This work illustrates the use of load transfer coupled physics analysis to solve a steady-state air flow-blade interaction problem, followed by modal analysis where natural frequency are obtained with two different approaches: deterministic and probabilistic. The numerical results are deduced from a finite element approximation of the coupled problem with a non-symmetric pressure/displacement formulation. Deterministic and probabilistic results are given and discussed.
