Abstract Using a (3+1)-D hydrodynamic model, CLVisc, we study the directed flow ( ) of light hadrons produced in Au+Au, Ru+Ru, and Zr+Zr collisions at 200 GeV. The evolution of tilted energy density, pressure gradient, and radial flow along the x-direction is systematically investigated. The counter-clockwise tilt of the initial fireball is shown to be a vital source of directed flow for final light hadrons. A good description of directed flow is provided for light hadrons in central and mid-central Au+Au and isobar collisions at the RHIC. Our numerical results show a clear system ...
