description The measurement of elliptic flow and higher-order flow harmonics of charged particles in $sqrt{s_{NN}}$ = 2.76 TeV Pb+Pb collisions with the ATLAS detector will be presented. Fourier harmonics v2 up to v6 were extracted with the event plane and two-particle correlation methods in a broad range of transverse momentum (0.5 GeV < pT < 20 GeV), pseudorapidity (|η|<2.5) and collision centrality (0-80%). Elliptic flow shows rapid rise with pT up to about 3 GeV followed by a decrease within range 3-8 GeV and then becomes weakly dependent at the highest pT. Similar trend is observed for higher-order harmonics. As a function of pseudorapidity a very weak dependence of all flow harmonics is measured. Results obtained with the two methods were found to be consistent and will be compared to measurements of other experiments at RHIC and LHC energies.
