We report our recent study on the global and local polarization of Λ hyperons in Au+Au collisions at RHIC-BES energies within the (3+1)- dimensional CLVisc hydrodynamics framework. We present our numerical results for the global polarization as a function of collision energies and the local polarization along the beam direction as functions of azimuthal angle in 20 − 50% centrality at √SNN = 7.7 GeV Au+Au collision energy. We have discussed the effects of initial conditions, Spin Hall effect and baryon diffusion.
