The transverse momentum (pT) and centrality dependence of the azimuthal anisotropy of second harmonics(υ2) are measured for charged hadron species at various collision systems and energies such as √SNN = 62.4 and 200 GeV in Cu + Cu and Au + Au collisions and at √SNN = 200 GeV in Cu + Au collisions by the PHENIX experiment at RHIC. The higher order anisotropy (υ3) are also measured for charged hadron at √SNN = 200 GeV in Cu + Cu, Au + Au and Au + Cu collisions. From these systematic study, we found that the all results are consistent with eccentricity scaling, quark number + KET scaling and Npart1/3) scaling except at small Npart in Cu + Cu at 62.4 GeV. Taking these scaling (quark number, KET, eccentricity and Npart1/3) into account, there is a universal scaling for π/K/p υ2 with different energies, collision sizes and particle species.
