The Fluid-Solid Interaction Analysis Of An Airfoil Based On ANSYS

Fluid-Structure interaction is the interaction problems between the structural and thefluid, It’s related to the biological engineering, the aerospace, the mechanical engineering, thehydraulic engineering and so on. The basic principles of Fluid-Structure interaction and themain method to solve the Fluid-Structure interaction problems were introduced in this paper,then the cross-section and variable cross-section models were introduced under the conditionsof the multi-angle, and there were a brief introduction to the basic steps, methods andprecautions in solving Fluid-Structure interaction question based on ANSYS. This wholepaper is focused on solving how to use ANSYS to achieve the unidirectional and bidirectionalFluid-Structure interaction analysis methods.The research is based on ANSYS-Workbench13.0, the ANSYS-Static structural andCFX have the connector. The unidirectional fluid-structure interaction analysis wasresearched and there is a detailed description about the variable cross-section subsonic airfoilwith the multi-angle, and the unidirectional and bidirectional Fluid-Structure interactionanalysis were researched about the cross-section subsonic airfoil with the multi-angle. Theresults obtained were used to analysis, comparison and the mechanical’s strength check. Thenthe relevant data of the unidirectional and bidirectional Fluid-Structure interaction wereobtained and there were the comparison and the advantages and disadvantages based on them.
