阻性压力梯度驱动turbulence流动结构的拓扑表征

Topological characterization of flow structures in resistive pressure-gradient-driven turbulence

Benjamin A. Carreras, Irene Llerena, Luis Garcia, Ivan Calvo

摘要:

湍流的可视化是理解湍流动力学和诱导输运的有力工具。然而,它没有提供所观察到的结构的定量描述。本文给出了流的拓扑的一种定量刻画方法。该技术,它可以应用于任何类型的湍流动力学,说明通过电阻气球不稳定性的例子。

英文摘要:

Visualization of turbulent flows is a powerful tool to help understand the turbulence dynamics and induced transport. However, it does not provide a quantitative description of the observed structures. In this paper, an approach to characterize quantitatively the topology of the flows is given. The technique, which can be applied to any type of turbulence dynamics, is illustrated through the example of resistive ballooning instabilities.
