N2 - We experimentally investigated the hydrodynamic forces acting on finite-length circular cylinders in an oscillating flow. Forced surging tests were carried out on finite length circular cylinders whose ratio of length to diameter varied from 1 to 10. The drag coefficients, the added mass coefficients and the lift coefficients were obtained, and were compared with those of a 2-D circular cylinder and a finite-length circular cylinder with end plates. We also studied the flow fields around the circular cylinders using the hydrogen bubble technique.
