[L'exitation paramétrique des ondes sur la surface libre d'une couche horizontale de liquide]
Nous examinons l'instabilité dynamique d'une couche horizontale d'un liquide faisant des oscillations harmoniques verticales. L'utilisation des fractions continues nous a permis déviter les restrictions habituelles de petite viscosité et de fréquences presque résonnantes. Nous obtenons des résultats numériques pour un large domaine des paramètres (la viscosité, l'amplitude et la fréquence des oscillations, la profondeur de la couche).
We consider the dynamical stability of horizontal fluid layer, performing harmonic oscillations in vertical direction. The continued fractions approach allowed us to avoid the conventional restriction to the case of small viscosity and almost-resonant frequencies. Our numerical results cover a wide range of the parameters (viscosity, amplitude and frequency of the oscillation, and depth of the layer).
