Abstract

The effects of turbulence intensity (Tu = 0.5% to 10%), normalized integral length scale (f⌐/D = 0.56 to 1.28, where D is the diameter of the cylinder), and Reynolds number (6.7~103 ≲ Re ≲ 1.2~104) on the drag and lift force coefficients, C_D and C_L, of two staggered circular cylinders were experimentally investigated. The longitudinal and transverse spacing between the centres of two identical cylinders, L/D and T/D, were kept constant at 4 and 1, respectively. At Tu = 4%, increasing f⌐/D dramatically changes C_D. However, the difference diminished when Tu ≳ 7%. f⌐/D = 0.56 has an insignificant effect on C_L. Increasing Re has a negligible effect on the force coefficients. When f⌐/D ≲ 1, with increasing Tu from 4% to 7%, the C_D increases and remains constant beyond 7%. When f⌐/D = 1.28, with increasing Tu from 4% to 7%, the C_D decreases and remains constant beyond 7%.
