Searching for chaotic deterministic features in laboratory water surface waves

Autor: M. Joelson, Th. Dudok de Wit, Ph. Dussouillez, A. Ramamonjiarisoa

Publikováno v: Nonlinear Processes in Geophysics, Vol 7, Iss 1/2, Pp 37-48 (2000)

The dynamic evolution of laboratory water surface waves has been studied within the framework of dynamical systems with the aim to identify stochastic or deterministic nonlinear features. Three different regimes are considered: pure wind waves, pure

Random fields of water surface waves using Wiener–Hermite functional series expansions

Autor: Maminirina Joelson, Alfred Ramamonjiarisoa

Publikováno v: Journal of Fluid Mechanics. 496:313-334

Random motions of irrotational gravity water surface waves on deep water are formulated using the so-called Wiener–Hermite functional series expansion, based on the ‘ideal random process’, i.e. the white noise. Such a procedure is known to diff

A non-linear second-order stochastic model of ocean surface waves

Autor: Alfred Ramamonjiarisoa, Maminirina Joelson

Publikováno v: Oceanologica Acta (0399-1784) (Gauthier-villars/editions Elsevier), 2001-09, Vol. 24, N. 5, P. 409-415

This paper deals first with the mathematical formulation of a non-linear second-order stochastic model of free irrotational ocean surface wave on deep water. Then, the case of wave motion of zero bandwidth is treated to illustrate the model. On the b

On the kinematics of short waves in the presence of surface flows of larger scales

Autor: A. Ramamonjiarisoa

Publikováno v: Journal of Fluid Mechanics. 298:249-269

When the resonance condition is satisfied, i.e. that the local group velocity of short surface waves matches the local velocity associated with a larger-scale surface flow, it is known that the short waves are reflected or trapped by the flow. A typi

Action of an adverse current on the shape of deep water surface waves

Autor: F. Bartholin, P. Bonmarin, A. Ramamonjiarisoa

Publikováno v: Experiments in Fluids. 18:438-444

It is well established that the shape of surface waves changes when waves meet a current. The effect of an adverse current is particularly interesting from a practical point of view.
