可视化已经发展成一种使用数学分析来获得和呈现重要数据属性的趋势。在三维流体流动中，工程师们对几个重要特征感兴趣。一种类型是流体长时间停留的再循环区。这在燃烧问题中起着关键作用，因为再循环允许完成通常具有比流体动力学更小的时间尺度的化学反应。这种回流区的强指标是在稳定矢量场或非稳定数据的时间步长中的循环流线。本文提出了一种通过分析接近它们的流线来检测这种环路的方法。
Visualization has developed a tendency to use mathematical analysis to obtain and present important data properties. In three-dimensional fluid flows, engineers are interested in several important features. One type are recirculation zones where the fluid stays for a long time. This plays a key role in combustion problems since recirculation allows a completion of chemical reactions which usually have a smaller time scale than fluid dynamics. Strong indicators for such recirculation zones are looping streamlines in a steady vector field or in the time steps of unsteady data. The article presents a method for the detection of such loops by analyzing streamlines approaching them.
