Abstract：
The transverse flow in heavy ion collisions can be characterized by the azimuthal anisotropy of the final state particles. A clear signature of the azimuthal correlation between directed and elliptic flow is evidenced in the model calculations . It is found that the azimuthal correlation is sensitive to the type of elliptic flow. The collective transverse expansion in coordinate space affects the azimuthal distributions of the final state particles in momentum space and the space-momentum correlation would develop. The study indicates that the behaviour of elliptic flow in different events depends on the evaluation of event-by-event dynamical fluctuations.
