For the flow around a rectangular cylinder, fluid-dynamic characteristics change according to the side ratio D/H, where the height of cylinder is defined as Hand the depth as D, and Reynolds number Re=U_∞H/v, where U_∞ is uniform flow velocity and v is kinetic viscous coefficient. In the present study we carried out a three-dimensional turbulent flow calculation, using the large eddy simulation (LES) with the standard Smagorinsky model, to solve the flow around rectangular cylinders with side ratios D/H of 0.6, 1, 2.5, 3 and 6. We then quantitatively predicted sound generated from dipoles involved in pressure fluctuations on the cylinder surface, and studied the variation of sound level affected with the side ratios.
