[Les ondes à courtes crêtes interfaciales de gravité–capillarité]
Cet article présente une méthode dérivée de la formulation variationnelle de Whitham du problème des ondes interfaciales à courte crête de gravité–capillarité. Elle est développée pour la résolution du problème des ondes générées par la réflexion oblique des ondes interfaciales sur une paroi verticale. La méthode de Whitham n’est pas modifiée, mais des calculs sont effectués et organisés pour produire une méthode qui a été appliquée à un certain nombre de cas démontrant l’efficacité et la flexibilité de l’approche. La performance de la méthode est illustrée par plusieurs exemples, y compris le cas de la résonance harmonique.
This paper presents a method derived from Whitham’s variational formulation of the problem of interfacial capillary–gravity short-crested waves. It is developed for the resolution of the problem of waves generated by obliquely reflecting interfacial waves from a vertical wall. In essence, Whitham’s method is not changed, but computations are performed and arranged to produce a method that has been applied to a number of cases demonstrating the effectiveness and the flexibility of the approach. The performance of the method is illustrated in several examples including the case of harmonic resonance.
