Abstract
The natural frequencies and damping rates of surface waves in a
circular cylinder
with pinned-end boundary conditions are calculated in terms of the gravitational
Reynolds and Bond numbers, C−1 and B,
and the
slenderness of the cylinder Λ, in the limit C→0. We
consider
higher-order approximations that include the effect
of viscous dissipation in the Stokes boundary layers and the bulk. A comparison
with clean-surface experiments by Henderson & Miles (1994) shows a
satisfactory
agreement except for the first axisymmetric mode, which exhibits a 26%
discrepancy.
The much larger dramatic discrepancy of former theoretical predictions
is hereby
improved and explained.
