Experimental Determination of Heave Added Mass and Damping of Two-Dimensional Bulbous Cylinders at the Free Water Surface.
Abstract
Experimental investigations were made on several two-dimensional models to determine the hydrodynamic coefficients of heave motion. The series of cylindrical models representing small waterplane area twin hull configurations were oscillated vertically at the free water surface at various amplitudes. The results, presented in this report, indicate some significant force nonlinearity with amplitude. Both added mass and damping were appreciably affected by cross sectional hull geometry and somewhat by strut thickness. Draft variations least influenced the coefficients of heave motion. (Author)
