Abstract:	The in-plane, out-of-plane and longitudinal components of the collective flow are extracted from the BUU simulation for⁴⁰Ar+²⁷Al collision in intermediate energy domain. It is found that the in-plane collective flow changes from a negative value to a positive value around 85 MeV/u. The flow angles are estimated by the in-plane and longitudinal components of the collective flow, and the rotational behavior in addition to the inplane flow is also found by the asymmetry of the azimuthal distribution in the calculation.
