Fluid-Structure Interaction in a Stirred Vessel Equipped with a Rushton Turbine

In this paper, a problem of fluid-structure interaction in a mixing vessel equipped with a Rushton turbine is solved with partitioned coupled fluid-structure interaction computational analysis. The computational fluid dynamics (CFD) code, based on the finite volume method, is used for determination of the flow field in the mixing vessel. The results in form of pressure distribution are then applied to the blade model, which is then analyzed with the computational structure dynamics (CSD) code, based on the finite element method. The resulting displacement is evaluated. The proposed procedure can be effectively used for optimization of structures with significant fluid flow influences. The comparison of the velocity profile with the results founded in the literature shows a good comparison. This proves the validity of the numerical method.
