Aerodynamically-driven rupture of a liquid film by turbulent shear flow

Abstract

The rupture of a liquid film due to co-flowing turbulent shear gas flows is studied using a volume-of-fluid method. This was done by ``sandwiching'' the film between two fully developed boundary layers from a turbulent channel simulation. Previous theoretical work has indicated that aerodynamic forces drive its evolution. A classical aerodynamics approach is employed to quantify the role of the inviscid lift and drag forces over the deforming film, which, while suggested by previous authors, has not been systematically studied before.
