摘要

CFD(计算流体动力学)中的数值运算结果可视化后处理是数值模拟的重要组成之一。MATLAB是一种用途较为广泛的开发工具,其图形功能十分强大,做到运算结果可视化十分方便。本文阐述了用MATLAB访问数据库的方式及流场绘制方式,利用MATLAB开发出了基于CFD数据库的流场可视化程序,并且使用开发的流场可视化程序依据后台阶流动的数值运算结果绘制了后台阶流动的流场,绘图实例能较为准确地反映流场局部的细节。
        Visualization post-processing of numerical operation results in CFD(Computational Fluid Dynamics) is one of the important components of numerical simulation. MATLAB is a widely used development tool. Its graphics function is very powerful and visualization of operation results is very convenient. In this paper, the way of accessing database by MATLAB and drawing flow field were described. A flow visualization program based on CFD database was developed by using MATLAB. The flow field of back-step flow was plotted by using the developed flow visualization program according to the numerical calculation results of back-step flow. The drawing example can reflect the local details of the flow field more accurately.
