A vast majority of the studies done in this field is on the prediction and reduction of noise caused by flow around circular cylinders [1]. Many researches have been done on the fluctuating forces resulting in vortex shedding from square cylinder [2-4]. Muller [5] investigated the details of the flow pattern around a square cylinder at three angles of attack 0˚, 13˚ and 45˚ using Large Eddy Simulation (LES) turbulence model. According to him, the flow pattern changes at a critical angle of attack alpha=13˚. At this angle of attack, the flow separation occurs at the front edge and the flow reattachment occurs at near the rear edge.

I don't understand this technical subject matter, so I will just do my best with your English.
