论文摘要
在这项工作中，我们为Bjorken流提供了分析和数值解，这是相对论流体动力学的标准基准，为重核之间碰撞中所产生的物质演变提供了一个简单的模型。我们考虑在A（2 + 1）和（3 + 1）Minkowski时空坐标系中工作的大量和无质量颗粒的相对论气体。最近开发的晶格动力学方案的数值结果与分析溶液非常一致。
In this work we provide analytic and numerical solutions for the Bjorken flow, a standard benchmark in relativistic hydrodynamics providing a simple model for the bulk evolution of matter created in collisions between heavy nuclei. We consider relativistic gases of both massive and massless particles, working in a ( 2 + 1 ) and ( 3 + 1 ) Minkowski space-time coordinate system. The numerical results from a recently developed lattice kinetic scheme show excellent agreement with the analytic solutions.
