Analysis of Non-Linear Wave-Body Interactions Using Finite Elements challenge to our community, where his contributions are highly significant, concerns the non-linear analysis of the interaction between steep waves and structures. The work summarised below is motivated by this challenge, and involves a collaborative project between the University of Oxford and UniGossamer 发表于 2025-3-28 21:12:00

Experiences from Comparing Theory with Environmental and Platform Dataplatform is 77500 tonnes including riser tensions, and the total tether tension at mean draft, 38.3 m, is about 29000 tonnes. The hull is made up of 4 circular columns with diameter 25 m, and a square ring pontoon. The column centre to centre distance is 76 m. The oil production capacity is about 19Bmd955 发表于 2025-3-29 17:09:58

Nonlinear Scattering of Long Waves by a Vertical Cylinderh λ, and wavenumber . = 2π/λ. Typical amplitudes are a few meters, with periods in the range of 8–11 seconds corresponding to wavelengths of 100–200m. In these conditions it is reasonable to use a perturbation expansion based on the assumption .. = O(ε), where ε < < 1. The first-order solution is li休息 发表于 2025-3-30 02:52:54

Mathematical Aspects of the Cauchy-Poisson Problem in Three Dimensionsnear the wave front. The solution obtained in that work involves uniform asymptotic expansions and our mathematical arguments are complicated. In the present note an attempt is made to explain these arguments. We shall be concerned with incompressible inviscid fluid of finite constant depth . under
