Shallow-water modeling and simulations of sheared liquid films in the context of aeronautical fuel injectors
Résumé
This work focuses on the numerical implementation of reduced order models to describe sheared thin liquid films in aeronautical fuel injectors. The model is based on the Shallow Water Equations [1], it accounts for partial wetting, surface tension, and wall curvature. Numerical coupling algorithms were implemented between the Eulerian film model and the Accurate Conservative Levelset (ACLS), which is a method used to describe the dynamics of the liquid interface. This work has been implemented in the YALES2 unstructured low-Mach number code [2] in a face-centered Finite Volume framework, and partially validated on 1D test cases.
