Viscous Relativistic Hydrodynamics
Abstract:
It is well known that ideal fluid dynamics is able to describe the collective flow patterns in central Au+Au collisions at high RHIC energies. However, this description breaks down for peripheral collisions or for collisions at lower energies. It is hoped that dissipative hydrodynamics could be used to explain these data and extract values of transport coefficients from the QGP. In this talk a set of equations is formulated and implemented numerically in order to perform causal dissipative hydrodynamic simulations of heavy-ion collisions using the second-order GENERIC structure. Assuming longitudinal boost invariance with arbitrary transverse expansion both the azimuthally symmetric 1+1 dimensional and 1+2 dimension cases are discussed. The viscous corrections to the anisotropic transverse flow and transverse momentum spectra are shown.
