摘要

The aim of the study is to know characteristics of a drag force acting on a sphere in an oblique arrangement of spheres, which may be influenced by the interval and the geometrical arrangement of spheres. In the study, a passing water tank was used as an apparatus and the drag force on a sphere was measured by using a load cell in a uniform flow. The flow around the spheres was also obtained by PIV. The experiment results show the effect of the front sphere on the drag force of the rear sphere through the velocity field in an oblique arrangement. Furthermore, the drag force acting on a sphere in a triangle arrangement of three spheres was also shown.
