Every one knows droplets pinning on the shower wall or at the car wind shield eventually growing, moving and forming rivulets due to gravity and aerodynamic forces. A numerical prediction of such movements is rather challenging, concerning many physical relevant details and models including: Multiphase Flows, Wetting, Turbulence, Multi Scales in Space and Time, Complex Geometries. Based on the open source library OpenFOAM, a Volume of Fluid solver for unstructured grids is developed… Show more Every one knows droplets pinning on the shower wall or at the car wind shield eventually growing, moving and forming rivulets due to gravity and aerodynamic forces. A numerical prediction of such movements is rather challenging, concerning many physical relevant details and models including: Multiphase Flows, Wetting, Turbulence, Multi Scales in Space and Time, Complex Geometries. Based on the open source library OpenFOAM, a Volume of Fluid solver for unstructured grids is developed with enhanced multiphase interface description, improved surface tension calculation, physical contact line and contact angle treatment, dynamic mesh refinement and dynamic load balancing and state of the art turbulence modelling.Our code is successfully validated with experiments of drops and rivulets on tilted plates and in turbulent channel flow.
