On examine différents aspects du mouvement d'une bulle qui oscille, en commençant par la formulation générale du problème et sa solution dans le cas d'une oscillation linéaire sphérique. On reprend alors ce problème au moyen d'une méthode variationnelle. On passe ensuite aux oscillations (sphériques) sous-harmoniques et non-linéaires puis aux oscillations non-sphériques et à une discussion de l'équation (non-linéaire) de Mathieu. Ensuite, la méthode variationnelle est utilisée pour étudier le couplage par interaction non-linéaire entre les oscillations sphériques sous-harmoniques et les oscillations non-sphériques. Enfin, on évoque le rôle éventuel du couplage non-linéaire dans les études expérimentales.Various aspects of an oscillating bub...
