流体力学和流动

Hydrodynamics and Flow

Tetsufumi Hirano, Naomi van der Kolk, Ante Bilandzic

摘要:

在这个课堂讲稿中,我们提出几个关于相对论性流体力学的主题,以及它在相对论性重离子碰撞中的应用。第一部分简要介绍了重离子碰撞中的相对论流体力学。第二部分介绍了相对论理想流体力学和粘性流体力学的形式和一些基本问题。在第三部分中,我们从基本观测量的一些基本检查开始,然后讨论集体流,特别是椭圆流,这是相对论能量下重离子碰撞中最令人兴奋的现象之一。接下来我们讨论如何用流体力学模型来描述重离子碰撞的动力学。最后,我们通过展示一些理想流体动力学计算的结果,并将它们与实验数据进行比较,来总结课堂讲稿的第三部分。

英文摘要:

In this lecture note, we present several topics on relativistic hydrodynamics and its application to relativistic heavy ion collisions. In the first part we give a brief introduction to relativistic hydrodynamics in the context of heavy ion collisions. In the second part we present the formalism and some fundamental aspects of relativistic ideal and viscous hydrodynamics. In the third part, we start with some basic checks of the fundamental observables followed by discussion of collective flow, in particular elliptic flow, which is one of the most exciting phenomenon in heavy ion collisions at relativistic energies. Next we discuss how to formulate the hydrodynamic model to describe dynamics of heavy ion collisions. Finally, we conclude the third part of the lecture note by showing some results from ideal hydrodynamic calculations and by comparing them with the experimental data.
