摘      要：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 *** consider relativistic gases of both massive and massless particles,working in a(2+1)and(3+1)Minkowski space-time coordinate *** numerical results from a recently developed lattice kinetic scheme show excellent agreement with the analytic solutions.
