This project investigates how turbulence determines the diffusion properties of particles, how the intermittence of the underlying turbulence affects diffusion, and how these effects depend on the energy of the particles. Here, artificial turbulence is generated to simulate particle transport in these realistic turbulent fields with the addition of a homogeneous component. In this way, the diffusion tensor as a function of the energy and turbulence ratio can be determined and made available to the projects in Research Area A. Furthermore, it is possible to quantify the influence of sub- and superdiffusion on astrophysical signatures.

该项目研究湍流如何决定颗粒的扩散特性，底层湍流的不稳定性如何影响扩散，以及这些影响如何取决于颗粒的能量。在这里，人工湍流产生模拟粒子输运在这些现实的湍流场与添加一个均匀的组件。通过这种方式，可以确定作为能量和湍流比的函数的扩散张量，并将其提供给研究区域A中的项目。此外，它是可能的，以量化的影响，亚和超扩散的天体物理特征。
