Strip calculations for ship oscillation coupled response in regular waves
Zhongguo Jianchuan Yanjiu, 2018 [Objectives] The strip method is widely used in the sea-keeping design of ships, but the hydrodynamics are only evaluated for the mean-hull position,so heaving,pitching and rolling motions are not essentially coupled. [Methods] For the effective coupling

Comparisons between sediment transport models and observations made in wave and current flows above plane beds [PDF]
, 1997 As a part of the MAST2 G8-M Coastal Morphodynamics project, the predictions of four sediment transport models have been compared with detailed laboratory data sets obtained in the bottom boundary layer beneath regular waves, asymmetrical waves, and ...

CURRENT DEPTH REFRACTION OF REGULAR WAVES
Coastal Engineering Proceedings, 1984 The complete set of equations for the refraction of small surface gravity waves on large-scale currents over a gradually varying sea bed is derived and presented. Wave lengths, direction of propagation and wave heights are all determined along the so-called wave rays as solutions to ordinary, first-order differential equations.

Regularity of rotational travelling water waves [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Several recent results on the regularity of streamlines beneath a rotational travelling wave, along with the wave profile itself, will be discussed. The survey includes the classical water wave problem in both finite and infinite depth, capillary waves and solitary waves as well.

Superharmonic instability for regularized long-wave models*
Nonlinearity, 2022 Abstract We examine the spectral stability and instability of periodic traveling waves for regularized long-wave models. Examples include the regularized Boussinesq, Benney–Luke, and Benjamin–Bona–Mahony equations. Of particular interest is a striking new instability phenomenon—spectrum off the imaginary axis extending into infinity. The

Lattice symmetry breaking perturbations for spiral waves [PDF]
, 2014 Spiral waves in two-dimensional excitable media have been observed experimentally and studied extensively. It is now well-known that the symmetry properties of the medium of propagation drives many of the dynamics and bifurcations which are ...
