| description | We provide numerical evidence that the Richtmyer-Meshkov (RM) instability contributes to
the cooling of a relativistic fluid. Due to the presence of jet particles traveling
throughout the medium, shock waves are generated in the form of Mach cones. The
interaction of multiple shock waves can trigger the RM instability, and we have found that
this process leads to a down-cooling of the relativistic fluid. To confirm the cooling
effect of the instability, shock tube Richtmyer-Meshkov instability simulations are
performed. Additionally, in order to provide an experimental observable of the RM
instability resulting from the Mach cone interaction, we measure the two particle
correlation function and highlight the effects of the interaction. The simulations have
been performed with an improved version of the relativistic lattice Boltzmann model,
including general equations of state and external forces. |
