(1+3)维纵横流的精确相对论理想流体力学解

Exact Relativistic Ideal Hydrodynamical Solutions in (1+3)D with Longitudinal and Transverse Flows

Jinfeng Liao, Volker Koch

摘要:

提出了一种求解(1+3)维相对论理想流体力学问题的新方法。纵向和横向径向流显式嵌入和流体动力学方程减少到一个单一的方程的横向速度场,这是更容易处理。作为一个应用,我们使用的方法来找到解析的所有可能的解决方案与功率依赖于适当的时间和横向半径。讨论了该方法在相对论性重离子碰撞中的可能应用以及可能的推广。

英文摘要:

A new method for solving relativistic ideal hydrodynamics in (1+3)D is developed. Longitudinal and transverse radial flows are explicitly embedded and the hydrodynamic equations are reduced to a single equation for the transverse velocity field only, which is much more tractable. As an application we use the method to find analytically all possible solutions with power dependence on proper time and transverse radius. Possible application to the Relativistic Heavy Ion Collisions and possible generalizations of the method are discussed.
