Abstract

We use a simple model consisting of energy-momentum tensor conservation and a Maxwell-Cattaneo equation for its viscous part to study nonlinear phenomena in a real relativistic fluid. We focus on new types of behavior without nonrelativistic equivalents, such as an entropy cascade driven by fluctuations in the tensor degrees of freedom of the theory. We write down the von Karman-Howarth equations for this kind of turbulence, and consider the correlations corresponding to fully developed turbulence.
完全发展的相对论性湍流
我们使用一个由能量动量张量守恒和粘性部分的麦克斯韦-卡塔尼奥方程组成的简单模型来研究实际相对论流体中的非线性现象。我们关注的是没有非相对论等价物的新行为类型,例如由理论的张量自由度波动驱动的熵级联。我们写下了这种湍流的von Karman-Howarth方程,并考虑了与充分发展的湍流相对应的相关性。
