Numerical simulation of fluid-structure interaction FOR blade based on CFX and Workbench

Abstract

The important feature of fluid-structure interaction (FSI) is the interaction between the two-phase media. FSI calculation is processed based on CFX and Workbench. Firstly, DesignModeler is used to creat the solid blade with the single channel flow field. Secondly, the grids for the blade and the flow field are created through the unique grid system in Workbench. Finally, the model will be calculated by using the FSI method. The stress and displacement of blade, the velocity and pressure of flow field, and the changes of grid can be obtained. The simulation result is reasonable and has some reference value to the FSI analysisi.
