运输是流动过程中的一个重要现象。任何物质或性质，如染料、动量或热，都可以在流体中传输。现代实验流体力学和计算流体力学越来越关注输运结构。研究人员已经开发出许多有前景的方法来描述流场的动态输运行为。然而，事实证明，理解这一复杂现象的重要特征仍然很困难。特别是，房地产运输的性质不清楚，也很难解释。对流动传输进行有效的可视化分析仍然具有挑战性。在本文中，我们重点研究了物理特性的输运特性，并提出了一种可视化特性有限时间输运结构的方法。我们特别关注流体中的主要输送方式--平流。平流是指通过水流的宏观运动来输送某种物质或性质。
Transport is an important phenomenon underlying a flow process. Any substance or property such as a dye, momentum, or heat can be transported in a fluid. Modern experimental and computational fluid mechanics are increasingly concerned with transport structure. Researchers have developed many promising approaches to depict the dynamic transport behavior of flow fields. However, comprehending the important characteristics of this complex phenomenon has still proved difficult. Particularly, the nature of property transport is unclear and hard to interpret. Effective visual analysis of flow transport is still challenging. In this article, we focus on physical properties’ transport characteristics and propose an approach to visualize the properties’ finite-time transport structures. In particular, we focus on advection, the major transport mode in a fluid. Advection involves transport of some substance or property by the macroscopic motion of currents.
