TL;DR: In this paper, the problem of an accelerating potential flow past a group of stationary circular cylinders is considered using the method of images, and the problem is formulated so that the number and location of the cylinders is arbitrary so long as there is no overlap between adjacent cylinders.
Abstract: The problem of an accelerating potential flow past a group of stationary circular cylinders is considered using the method of images. The problem is formulated so that the number and location of the cylinders is arbitrary so long as there is no overlap between adjacent cylinders. Inertial and lift coefficients are determined for several different cylinder arrangements. The inertial coefficient for a cylinder can vary in either direction from its single-cylinder value of 2.0. The controlling factors on this variation are the relative geometric position of the cylinder within the group and its distance from its neighbors. These same factors determine, as is expected, the lift coefficient values. In two example configurations, there is even a drag-type force generated on an individual cylinder in the potential flow.

TL;DR: In this paper, a horizontal circular cylinder was experimentally measured to determine the influence of a plane boundary (e/D), A/D, and water depth (h/D) on these forces.
Abstract: Wave forces on a horizontal circular cylinder were experimentally measured to determine the influence of a plane boundary (e/D), water particle displacement (A/D), and water depth (h/D) on these forces. The transition from potential flow conditions to real flow conditions is considered. The variation of force coefficients of inertia, lift, and drag with respect to e/D, A/D, and h/D is identified.
