Abstract

DENICOL, G. S.; MOTA, Ph.; KODAMA, T.  and  KOIDE, T.. Causal structure of relativistic dissipative hydrodynamics. Braz. J. Phys. [online]. 2007, vol.37, n.1a, pp. 102-105. ISSN 1678-4448.  http://dx.doi.org/10.1590/S0103-97332007000100030.

We present a new formalism for the relativistic dissipative hydrodynamics consistent with causality. We start from the physical analysis of the irreversible currents according to the Landau-Lifshitz theory. Then, the irreversible currents are given by integral expressions which take into account the relaxation time. Only one additional parameter was introduced, the relaxation time, tR. We verified that the linearized equation of motion for small perturbations in the homogeneous, static background coincides with Hiscock-Lindblom.

Keywords : Viscosity; Dissipative phenomena; Relativistic hydrodynamics.
