The flow of charm is calculated in 2 + 1 ideal hydrodynamics by introducing the charge of cc pair assuming that the number of cc pairs is conserved in relativistic heavy ion collisions. It is found that the mean radial flow velocity of charm quarks is smaller than that of bulk matter by 10 ∼ 15% and the measured v2 of heavy-flavor electrons is reproduced up to pTe= 1.5 GeV/c in Au + Au collisions at Relativistic Heavy Ion Collider (RHIC). The same flow is applied to regenerated J/ψ and its v2 is discussed.
