Abstract
The hydrodynamic features of a falling cylinder into the water column is
investigated experimentally. The experiment consisted of dropping three
cylinders of various lengths into a pool where the trajectories were filmed
from two angles. The controlled parameters were, cylinder parameters
(length to diameter ratio, center of mass location), and initial conditions
(initial velocity, and drop angle). Results indicate that center of mass position
has the largest influence on the cylinder’s trajectory and that accurate
trajectory modeling requires the inclusion of both momentum and moment
equations. A statistical-dynamic model has been established to predict the
trajectories of the falling cylinders.
