The Coupled Damping Coefficients of a Symmetric Ship

摘要: Abstract : A study was made of a floating or submerged body with longitudinal and transverse symmetry, which is moving constant forward speed performing small oscillations. The analysis quite general in the sense that shape nature oscillations are unspecified, but it assumed linearized free-surface condition holds. With this assumption oscillatory velocity potential found terms an unknown Green's function, existence also assumed. This po tential then used to show symmetry properties cross-coupling damping coefficients. (Author)
