内燃机缸内流场信息图象观测处理的研究

Visualizations and Measurements of In-Cylinder Flow Patterns in Internal Combustion Engines

本文借助图象处理技术和数值计算方法，探索出一种使内燃机缸内流动纹影照片信息可视化的方法。利用这种方法可得到定性合理的流动显示图画。

An attempt has been made at the visualizations and the measurements of the in-cylinder flow patterns which have been derived from the distribution of density gradient recorded by the schlieren photos by rneans of the techniques of image processing and numerical calculation, with which the reasonable patterns of in-cylinder flows have been obtained.
