Due to the similarity to many engineering structure, the flow characteristics around the square cylinder has been studied for some time based on the experiment or Computational Fluid Dynamics (CFD). However in the past research for simplicity the inlet is assumed as the steady, which is conflict with reality. To conquer this problem, in this paper, the time varying inlet boundary condition based on ARMA model will be presented, from this proposed model, this inlet boundary realization procedure is presented, to study the flow characteristics around the bluff body, a 2D square cylinder is chosen as the analysis target, different turbulence intensity will be applied at the inlet boundary, the general aerodynamic parameters such as lift, drag coefficient, and velocity component value will be discussed. To study the aerodynamic parameters in the frequency domain, the velocity spectrum at different position around the square cylinder will be discussed; some conclusions based on the analysis result will be presented in the end.
