摘要

笔者从Ansys CFX软件流场计算的优势出发

说明了其是一款优良的计算流体力学（computational fluid dynamics

CFD）软件

并介绍该软件的一种动态流场计算方法及其可能存在的问题

即绘图软件与计算软件对几何面的识别存在误差。针对该问题

文中集成Workbench几何处理模块（design model

DM）、参数化驱动模块（parameter set）和脚本语言（scripting）进行解决。最后

以某高压断路器灭弧室实际流场动态计算为例

说明了该方法的可行性和合理性

可满足灭弧室设计初期工程设计需求。该方法有效避免了动网格计算中相邻时间步几何模型的识别问题

拓展了优化模块的使用功能

实现了运动部件的参数化;对于一般意义下的优化分析问题

该方法也提供了一种很好的参考思路。

Abstract

The advantages of the CFD software Ansys CFX in the flow field calculation are described. However

a possible problem may exist in a certain dynamic flow field calculation method of the software

i.e. there is an geometry identification error between CAD and CAE. In order to solve this problem

the Workbench geometric processing module

set parameter module and scripting command are integrated. Moreover

the actual dynamic flow field in arc interrupter of a high voltage circuit breaker is calculated

and the result verifies the feasibility and rationality of the proposed method. It is concluded that this method can effectively avoid the geometry identification error between two near calculation steps in the dynamic flow field calculation

extend the function of parameter set to achieve parametric design of relevant motion component

and provide a reference for common optimization problem.
