Abstract

The problem of calculating nonlinear two-dimensional free-surface potential flow about a circular cylinder rising to a free surface is solved numerically. The deeplysubmerged circular cylinder is accelerated smoothly from rest to a uniform vertical velocity. A boundary/integral-equation method is used to obtain free-surface elevations and streamlines about the rising cylinder for several final speeds. Results, including pressure forces, are compared with a cylinder rising to a rigid wall and a cylinder moving in an infinite fluid.
