The directed and elliptic flow in collisions of 112Sn + 112Sn at energies from 35 to 90 MeV/nucleon were studied in an isospin-dependent quantum molecule dynamics model (IQMD). With increasing incident energy, the directed flow rises from the negative flow to the positive flow. Its magnitude depends on the nuclear equation of state (EOS). However, the elliptic flow shows decrease with increasing incident energy and its magnitude is not very sensible to EOS. Systematic studies of the impact parameter dependence and cluster mass dependence were also performed. The study of directed flow at intermediate energies thus provides a means to extract the information on the nuclear equation of state.
