The scope of this Note is to show the results obtained for simulating the two-dimensional head-on collision of two solitary waves by solving the Navier–Stokes equations in air and water. The work is dedicated to the numerical investigation of the hydrodynamics associated to this highly nonlinear flow configuration, the first numerical results being analyzed. The original numerical model is proved to be efficient and accurate in predicting the main features described in experiments found in the literature. This Note also outlines the interest of this configuration to be considered as a test-case for numerical models dedicated to computational fluid mechanics.
Ce travail est consacré à l'étude numérique de la collision bidimensionnelle frontale de deux ondes solitaires par simulation numérique des équations de Navier–Stokes en formulation diphasique. L'intérêt de cette étude réside dans la démonstration de la capacité de l'outil numérique original à traiter efficacement ce problème d'onde hautement non-linéaire. Dans cette Note, les résultats numériques sont comparés aux résultats disponibles dans la littérature. Une première investigation de l'hydrodynamique de l'écoulement général est proposée. Il est ainsi démontré que cette configuration est d'une très grande utilité pour valider un code de simulation de mécanique des fluides numérique.
