具有记忆函数和色噪声的相对论性脉动流体动力学
Relativistic fluctuating hydrodynamics with memory functions and colored noises
摘要：
通过强调非线性和因果关系，建立了包含水动力波动的相对论耗散流体动力学。作为因果关系的结果，耗散电流成为动力学变量和噪声出现在本构方程的积分形式应该是有色的涨落耗散关系。然而，当噪声被假定为高斯噪声时，噪声在其微分形式上是白噪声。所得到的微分方程组在相对论性脉动流体力学的数值实现中是非常有用的。
英文摘要：
Relativistic dissipative hydrodynamics including hydrodynamic fluctuations is formulated by putting an emphasis on non-linearity and causality. As a consequence of causality, dissipative currents become dynamical variables and noises appeared in an integral form of constitutive equations should be colored ones from fluctuation-dissipation relations. Nevertheless noises turn out to be white ones in its differential form when noises are assumed to be Gaussian. The obtained ifferential equations are very useful in numerical implementation of relativistic fluctuating hydrodynamics.
