Using the event-by-event viscous hydrodynamicsVISH2+1withMC-Glauber,MC-KLN, andAMPTinitial conditions, we investigate the correlations of flow harmonics including the symmetric cumulantsand the normalized symmetric cumulantsinTeV Pb-Pb collisions. We findis sensitive to both initial conditions and the specific shear viscosity. Comparisons with the recent ALICE data show that our hydrodynamic calculations can qualitatively describe the data ofandfor various initial conditions, which demonstrate thatandare anticorrelated andandare correlated. Meanwhile, the predicted symmetric cumulants,, andreveal thatandare correlated andandare correlated, whileandare anticorrelated in most centrality classes. We also find thatis insensitive to, and is mainly determined by corresponding NSCɛ(3,2) from the initial state. In contrast, otherare influenced by both initial conditions and, which illustrates the nonlinear mode couplings in higher flow harmonics with.
