Many investigations had been done both numerically and experimentally, on the characteristics of multiple-arranged cylinders especially in terms of the induced fluid forces and responses caused by external fluid flows acting on them. This paper discusses the investigation result on induced drag of two cylinders helically wrapped around by triple rods with certain gap in air flow fields. The model cylinders were installed in the test section of a wind tunnel as a side-by-side arrangement and treated as roll supports at ends of the cylinders. The model was executed at subcritical regime of incoming uniform air flow acting perpendicular to the cylinders that related to Reynolds number of 3.9 × 104 and evaluated for different gaps between the cylinder of 1.75D, 2.0D, and 2.50D, respectively, where D is diameter of the bare cylinder. Load cells were used for measuring the drag occurring on the cylinders. For all gap variety evaluated results demonstrated that greater coefficient of drag (CD) happened in the two cylinders which was caused by more prominent interference between them. The CD increased greater than other gaps for the cylinder’s gap of 2.0D that was well confirmed against others relevant works. For this side-by-side configuration, the CD of the lower and upper cylinders significantly increased in contrast with the single cylinder case by 55.8% and 55.5%, respectively.
