近十年来，星际介质中的湍流一直是一个活跃的研究领域。在大多数情况下，数值模拟是选择的工具。然而，虽然市场上有许多模拟，但最终仍有一些问题没有得到回答。在本文中，我们研究了可压缩和不可压缩驱动对一些可能的星际介质场景中湍流光谱演变的影响。我们得出结论，驱动不仅影响可压缩与不可压缩分量的比值，而且影响湍流的各向异性。
Abstract Turbulence in the interstellar medium has been an active field of research in the last decade. Numerical simulations are the tool of choice in most cases. However, while there are a number of simulations on the market, some questions have not been answered finally. In this paper, we examine the influence of compressible and incompressible driving on the evolution of turbulent spectra in a number of possible interstellar medium scenarios. We conclude that the driving has an influence not only on the ratio of compressible to incompressible component but also on the anisotropy of turbulence.
