Abstract
The LES in curvilinear coordinate system are applied to the flow around a square cylinder in uniform and homogeneous turbulent flows. We use the statistical method proposed by Hoshiya to generate inflow turbulence. Firstly, we confirm the accuracy of the present computational results about the flow around a square cylinder in uniform flow. Next, the applicabilites of the present numerical method to prediction of aerodynamic characteristics of a square cylinder as a function of intensity of homogeneous turbulent flow, are shown. As a result, we show the present method can simulate the effect of turbulence intensity on the flow around a square cylinder.
