Relativistic hydrodynamics from Boltzmann equation with modified collision term (1303.1892v2)
Published 8 Mar 2013 in nucl-th, hep-ph, and physics.flu-dyn
Abstract: Generalizing the collision term in the relativistic Boltzmann equation to include nonlocal effects, and using Grad's 14-moment approximation for the single-particle distribution function, we derive evolution equations for the relativistic dissipative fluid dynamics and compare them with the corresponding equations obtained in the standard Israel-Stewart and related approaches. Significance of this generalization on hydrodynamic evolution is demonstrated in the framework of one-dimensional scaling expansion.
