摘要

流固耦合(FSI)的重要特征是两相介质之间的相互作用。FSI计算是基于CFX和Workbench进行的。首先,使用DesignModeler创建具有单通道流场的固体叶片。其次,通过Workbench中独特的网格系统对叶片和流场进行网格划分;最后,采用FSI法对模型进行计算。得到叶片的应力和位移、流场的速度和压力以及栅格的变化。仿真结果合理,对FSI分析具有一定的参考价值。

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