Realization of Streamline Visualization Based on MATLAB and CFD Database

摘要

The CFD numerical calculation result visualization is an important part of the numerical simulation. Streamline visualization is an important technique for flow field visualization. Matlab is a widely used development tool with powerful graphics capabilities. It is very easy to realize the visualization of calculation result with Matlab. The method to access database and the method to draw streamline with MATLAB were elaborated. The streamline visualization program based on CFD database was developed with MATLAB. The streamline of backward facing step flow is drawn based on the numerical calculation result with the developed streamline visualization program. The location conditions of flow field in the protract example are accurately shown.
