The three dimensional simulations of the flow around cylinder at Re = 3900 by using the large eddy simulation solver in OpenFOAM are presented in this paper. Extensive analysis of characteristics and properties of the turbulent wake flow behind the cylinder is also given. The presented numerical results show that the large eddy simulation employed could capture the subtle structure in the flow field. All of the presented numerical results are in good agreement with the experimental ones, which could help us to understand the complicated 3D turbulent wake flow around a 3D cylinder.
