Summary

The paper describes a test that was carried out to check the implementation of viscous stresses in a 3D code that can model flows with a free-suface. A pair of counter rotating vortices are allowed to travel upwards and along a free-surface. The results, which are compared with those of a recently carried out independent simulation, provide an important check on a code that has been specifically developed to model turbulence in flows that have a deformable free-surface.

Résumé

L’article décrit un essai réalisé pour vérifier la mise en oeuvre d’un code 3D de contraintes visqueuses destiné á la modélisation des écoulements á surface libre. Une paire de tourbillons tourmant en sens opposés peuvent se déplacer vers le haut et le long de la surface libre. Les résultats, qui sont comparés á ceux d’autres simulations menéea indépendamment, foumissent une validation significative d’un code développé dans le but de modéliser la turbulence d’écoulement comportant une surface libre deformable.
