Dissipative fluids out of hydrostatic equilibrium
نویسنده
چکیده
In the context of the Müller-Israel-Stewart second order phenomenological theory for dissipative fluids, we analyze the effects of thermal conduction and viscosity in a relativistic fluid, just after its departure from hydrostatic equilibrium, on a time scale of the order of relaxation times. Stability and causality conditions are contrasted with conditions for which the ”effective inertial mass” vanishes. ∗On leave from Departamento de F́ısica, Facultad de Ciencias, Universidad Central de Venezuela, Caracas, Venezuela and Centro de Astrof́ısica Teórica, Mérida, Venezuela.

متن کاملStable First Order
We propose a novel first order, local equilibrium approach to special relativistic dissipative hydrodynamics. Using a particular separation of internal and flow energies we remove all known instabilities of the linear response approximation. This result provides a stable inclusion of heat conductivity into the description of first order viscous relativistic fluids.
متن کاملComment I on "Possible experiment to check the reality of a nonequilibrium temperature"
where s,z(u) is the local-equilibrium entropy, T the local-equilibrium absolute temperature, q the heat flux, A, Some of the most basic questions in nonequilibrium thermodynamics are those concerning the fundamental thermodynamic concepts, namely, the definition and meaning of entropy and of absolute temperature out of equilibrium. Most of the nonequilibrium thermodynamic theories have assumed ...
متن کاملGeneralized Entropy and Transport Coefficients of Hadronic Matter
We use the generalized entropy four-current of the Müller-Israel-Stewart (MIS) theories of relativistic dissipative fluids to obtain information about fluctuations around equilibrium states. This allows one to compute the non-classical coefficients of the entropy 4-flux in terms of the equilibrium distribution functions. The Green-Kubo formulae are used to compute the standard transport coeffic...
متن کاملGeneralized Green-Kubo expressions for transport coefficients in fluids with impulsive, dissipative, stochastic and conservative interactions
– We present generalized Green-Kubo expressions for thermal transport coefficients μ in fluid-type systems, of the generic form, μ = μ∞ + ∫ ∞ 0 dt V −1〈Jǫ exp(tL)J〉0, i.e. a sum of an instantaneous transport coefficient μ∞, and a time integral over a time correlation function in a state of thermal equilibrium between a current J and a transformed current Jǫ. The streaming operator exp(tL) gener...
