The variation of multiple circular cylinders' drag coefficient was investigated using numerical methods. Moreover, the particle tracking simulation was also performed to show the flow structure and how particles move inside the cylinder array. It was found that the density and location of cylinders have a significant influence on the fluid forces, flow structure, and particle movement inside them.
