[en] Studied herewith is the vorticity patterns in relativistic heavy ion collisions with respect to the collision energy. The collision energy is related to the chemical potential of the thermal - statistical models that assume chemical equilibrium after the relativistic collision. Used herewith is the multiphase transport model (AMPT) to study the vorticity. The flow patterns related to the bulk viscosity and the shear viscosity at different collision energies have been studied. It has been found that the shear viscosity obtained is almost a constant with a small decrease at higher collision energies. The elliptic flow as it is related to viscous effects in the final stages after the collision has been studied
