Added Mass and Damping for Ice Floes by Long Water Wave Theory
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 113, Issue 5
Abstract
Added mass and damping for ice floes are important parameters in determining floe collision forces with arctic structures. They are measures of the hydrodynamic resistance to the change of the floe motion. An analytical approach is presented based on long water wave theory to determine: (1) The added mass and damping for a circular ice floe for a wide frequency range and with general floe movements including two translations (surge and heave) and one rotation (pitch); and (2) the hydrodynamic impulse function on a circular ice floe resulting from its impact with a rigid structure. The governing equations are solved by: (1) The Fourier transformation; or (2) the Laplace transformation method, depending on the problem. Closed‐form solutions and plots are provided for estimating the added mass, damping, and the hydrodynamic impulse function for a circular ice floe.
