THE 3-D STUDY ON FLOW AROUND TWO WALL-MOUNTED CYLINDERS IN SIDE BY SIDE ARRANGEMENT

ABSTRACT
To investigate the characteristics of flow over two finite-height cylinders in side-by-side arrangement, 3-D numerical simulations are performed using the CFD technology for gap ratios (G = S/d, where d is the diameter of the cylinders, and S is the separation gap between the cylinders) between 1 and 4 at a Reynolds number of 100. The height-to-diameter ratio (h/d = 8, where h is the height of the cylinder) is fixed at 8. The drag and lift coefficients of the cylinders, as well as the Strouhal number are presented and compared with those of their 2-D counterparts. Our re­sults show that the wake of the cylinders indicates a transition from the anti-phase state to the in-phase state at large gap ratios, accompanied by a decrease in the lift coefficients of the cylinders.
