Viscous hydrodynamics with bulk viscosity -- uncertainties from relaxation time and initial conditions
arXiv:0907.2262 · doi:10.1016/j.nuclphysa.2009.10.041
Abstract
Bulk viscosity suppresses elliptic flow v_2, as does shear viscosity. It can thus not be neglected when extracting the shear viscosity from elliptic flow data. We here explore uncertainties in the bulk viscous contribution to viscous v_2 suppression that arise from presently uncontrolled uncertainties in the initial value of the bulk viscous pressure and its microscopic relaxation time.
