Development of an Aft Boundary Condition for a Horizontally Towed Flexible Cylinder

The method of characteristics is used to develop an aft boundary condition for the linear transverse dynamics of a towed neutrally buoyant flexible cylinder, extending a previous approach to more general numerical methods (e.g., finite differences, finite elements, etc.). The boundary condition is located at the critical point on the cylinder (i.e., where the tension and hydrodynamic forces balance) instead of at the free end. This avoids the region where bending terms become important, and it removes the problem of modeling the instabilities in the region near the free end. The approach can also be extended to the nonlinear case.
