This thesis focuses on studying the dynamics of relativistic heavy-ion collisions at intermediate collision energies, whose experiments were presently conducted in the Beam Energy Scan (BES) program at the Relativistic Heavy-Ion Collider (RHIC). Building upon the open-source theoretical framework iEBE-MUSIC, we implement the calculation of the flow vorticity tensor $\omega^{\mu\nu}$ and its associated coupling terms in the evolution of viscous shear stress tensor and bulk viscous pressure during the hydrodynamic simulations. Using this numerical framework, we make quantitative analysis of the longitudinal and transverse dynamics of the fireballs created in the heavy-ion collisions with experimental measurements at RHIC. Off-central collisions, coincide with large angular momentum. We explore the evolution of system's global angular momentum and four types of local flow vorticity during the hydrodynamic evolution.
