Description

In this talk we focus on the anisotropic flows produced in the ultrarelativistic heavy ion collisions. Recently it has been possible to measure the anisotropic flows event by event up to the 6-th harmonics. These observables are sensitive to the shear viscosity of the plasma. In this talk we discuss the build up of the elliptic flows and high order harmonics $v_n=<cos(n\varphi )>$ within a transport approach at fixed shear viscosity to entropy density ratio $\eta /s$ and with initial state fluctuations. We discuss the effect of a temperature dependent $\eta /s$ on $v_n$ and their correlations with the initial eccentricities ${ϵ}_n$ at RHIC energies for Au+Au collisions at $\sqrt{s}=200GeV$ and LHC energies for $Pb+Pb$ collisions at $\sqrt{s}=2.76TeV$.
