### Description

For various centrality selections, we will present $v_{2}$ and $v_{3}$ measurements as a function of particle species and transverse momentum for several beam energies and system size. The longitudinal flow decorrelation $r_n(\eta,\eta_{ref} )$ $(n=2, 3)$ will be also presented at three different collision energies.

Investigating the beam-energy and collision-system size dependence of the anisotropic flow measurements (high momentum $v_{n}$, identified hadron $v_{n}$, and longitudinal flow decorrelation) is expected to provide crucial insights on the initial conditions and the transport properties of the QGP.
