... ABSTRACT Nonhnear axisymmetric viscous and inviscid solutions corresponding to heave oscillation of a submerged vertical cylinder are presented in this paper. The fully nonlinear free-surface flow problem is solved using finite-difference method based on curvilinear coordinates. A primitive...

... for the analysis is based on an analysis of the resonant condition and a wake-oscillator model. Periodical variations of tether's tension caused by heave oscillation of TLP play the role of a parametric excite to vortex induced vibration, and make it more complicated. In this paper, the conditions of structure...

... surface. There clearly exists a critical non-dimensonal frequency near ω 2 a/g = 0.3 for the heave oscillations near the free surface, as was measured previously but not predicted by a potential theory for a long, 2- D horizontal cylinder in intinite depth (Chung, 1977). Also, negative added mass...
