Ultrarelativistic fluid dynamics

چکیده
This is the first of two papers examining the critical collapse of spherically symmetric perfect fluids with the equation of state P = (Γ − 1)ρ. Here we present the equations of motion and describe a computer code capable of simulating the extremely relativistic flows encountered in critical solutions for Γ ≤ 2. The fluid equations are solved using a high-resolution shock-capturing scheme based on a linearized Riemann solver.

Nonequilibrium fluid-dynamics in the early stage of ultrarelativistic heavy-ion collisions
To describe ultrarelativistic heavy-ion collisions we construct a three-fluid hydrodynamical model. In contrast to one-fluid hydrodynamics, it accounts for the finite stopping power of nuclear matter, i.e. for nonequilibrium effects in the early stage of the reaction. Within this model, we study baryon dynamics in the BNL-AGS energy range. For the system Au+Au we find that kinetic equilibrium b...
متن کاملSecond-order dissipative fluid dynamics for ultrarelativistic nuclear collisions.
The Müller-Israel-Stewart second-order theory of relativistic imperfect fluids based on Grad's moment method is used to study the expansion of hot matter produced in ultrarelativistic heavy-ion collisions. The temperature evolution is investigated in the framework of the Bjorken boost-invariant scaling limit. The results of these second-order theories are compared to those of first-order theori...
متن کاملOn the symmetries of the 1 + 1 dimensional relativistic fluid dynamics
A very intuitive description of nucleus-nucleus collision phenomena is provided by the relativistic fluid dynamics. We consider a 1+1 dimensional relativistic imperfect fluid flow to approximate the high energy heavy ion collision. The article investigates the application of the continuous symmetry group on the relativistic fluid energy-momentum tensor conservation equations in the ultrarelativ...
متن کاملA pr 1 99 6 Spherically symmetric perturbation of ultrarelativistic fluid in homogeneous and isotropic universe
A solution of the linearized Einstein’s equations for a spherically symmetric perturbation of the ultrarelativistic fluid in the homogeneous and isotropic universe is obtained. Conditions on the boundary of the perturbation are discussed. The examples of particlelike and wave-like solutions are given.
متن کاملOn Dynamics of Relativistic Shock Waves with Losses in Gamma-ray Burst Sources
Generalization of the self-similar solution for ultrarelativistic shock waves (Blandford & McKee, 1976) is obtained in presence of losses localized on the shock front or distributed in the downstream medium. It is shown that there are two qualitatively different regimes of shock deceleration, corresponding to small and large losses. We present the temperature, pressure and density distributions...
متن کاملTidal Dynamics of Relativistic Flows Near Black Holes
We point out novel consequences of general relativity involving tidal dynamics of ultrarelativistic relative motion. Specifically, we use the generalized Jacobi equation and its extension to study the force-free dynamics of relativistic flows near a massive rotating source. We show that along the rotation axis of the gravitational source, relativistic tidal effects strongly decelerate an initia...
