Description

vSPheRIO is a new second order viscous hydrodynamic code for ultrarelativistic heavy ion collisions that can be consistently run on an event-by-event basis. This code, which is the viscous generalization of the well known SPheRIO code \cite{Aguiar:2000hw}, solves second order viscous hydrodynamic equations. In this talk, we use vSPheRIO to investigate the time evolution of a boost invariant QGP, with a realistic equation of state \cite{Huovinen:2009yb}, and temperature dependent $\eta/s$ and $\zeta/s$ \cite{NoronhaHostler:2008ju}. Results for the anisotropic flow coefficients $v_2$ to $v_5$ obtained within this setup are compared to other viscous hydrodynamic calculations that involved constant $\eta/s$ and $\zeta/s$ ratios \cite{Schenke:2011bn}. %\cite{Aguiar:2000hw} \bibitem{Aguiar:2000hw} C.~E.~Aguiar, T.~Kodama, T.~Osada and Y.~Hama, %``Smoothed particle hydrodynamics for relativistic heavy ion collisions,'' J.\ Phys.\ G G {\bf 27}, 75 (2001) [hep-ph/0006239]; Y.~Hama, T.~Kodama and O.~Socolowski, Jr., %``Topics on hydrodynamic model of nucleus-nucleus collisions,'' Braz.\ J.\ Phys.\ {\bf 35}, 24 (2005) [hep-ph/0407264]; R.~Andrade, F.~Grassi, Y.~Hama, T.~Kodama and O.~Socolowski, Jr., %``On the necessity to include event-by-event fluctuations in experimental evaluation of elliptical flow,'' Phys.\ Rev.\ Lett.\ {\bf 97}, 202302 (2006) [nucl-th/0608067]. %\cite{Huovinen:2009yb} \bibitem{Huovinen:2009yb} P.~Huovinen and P.~Petreczky, %``QCD Equation of State and Hadron Resonance Gas,'' Nucl.\ Phys.\ A {\bf 837}, 26 (2010) [arXiv:0912.2541 [hep-ph]]. %%CITATION = ARXIV:0912.2541;%% %\cite{NoronhaHostler:2008ju} \bibitem{NoronhaHostler:2008ju} J.~Noronha-Hostler, J.~Noronha and C.~Greiner, %``Transport Coefficients of Hadronic Matter near T(c),'' Phys.\ Rev.\ Lett.\ {\bf 103}, 172302 (2009); H.~Niemi, G.~S.~Denicol, P.~Huovinen, E.~Molnar and D.~H.~Rischke, %``Influence of the shear viscosity of the quark-gluon plasma on elliptic flow in ultrarelativistic heavy-ion collisions,'' Phys.\ Rev.\ Lett.\ {\bf 106}, 212302 (2011); G.~S.~Denicol, T.~Kodama, T.~Koide and P.~Mota, %``Effect of bulk viscosity on Elliptic Flow near QCD phase transition,'' Phys.\ Rev.\ C {\bf 80}, 064901 (2009). %\cite{Schenke:2011bn} \bibitem{Schenke:2011bn} B.~Schenke, S.~Jeon and C.~Gale, %``Higher flow harmonics from (3+1)D event-by-event viscous hydrodynamics,'' Phys.\ Rev.\ C {\bf 85}, 024901 (2012) [arXiv:1109.6289 [hep-ph]]. %%CITATION = ARXIV:1109.6289;%%
