摘要
基于ANSYS Workbench与CFX有限元分析软件,采用双向流固耦合方法,以横向流作用下的单根直管为基本分析对象,建立三维流固耦合模型。利用Meshing划分不同网格来研究网格划分对单管的流致振动数值模拟的影响。以横向均匀来流下单管为例,给出了合理的边界层网格划分方式及合理的时间步长。
Based on ANSYS Workbench and CFX finite element analysis software, a threedimensional fluid-solid coupling method was established to analyze the single straight tube under the transverse flow. Workbench Meshing was used to divide different types of grids,and the effect of different gridding on the numerical simulation of flow-induced vibration system was considered. With the two-way fluid-solid coupling method,a reasonable boundary layer gridding meshing and time step were given for a single tube with transverse flow.
