This workshop instructs researchers on the latest advances in the computational modelling of the interfacial dynamics of capillary two-phase flow phenomena using the CFD-based frameworks of VOF, LS, ALE-FEM, and Molecular Dynamics methods. Lectures are complemented with practical hands-on sessions.Content
The workshop is composed of the following main parts:
- Mathematical basis of two-phase flow, Computational Fluid Dynamics and Molecular Dynamics approximations, surface tension, and phase change;
- Eulerian techniques with diffused interface methods to advect the interface, Volume Of Fluid (VOF) and Level Set (LS) methods, implicit advection of a color function, geometrical reconstruction and interface compression of the interface, interface topology calculation, surface tension and phase change modelling on a VOF and LS framework;
- Eulerian techniques for two-phase flows advecting marker points to preserve interface sharpness, numerical methods to advect marker points, mass conservation, front remeshing;
- Arbitrary Lagrangian-Eulerian (ALE) finite-element methods (FEM) for two-phase flows, finite element formulation, use of python language to build simplified models, update of the mesh morphology, moving boundaries;
- Molecular Dynamics (MD) simulations of liquid-vapor interfaces and phase change, structure and stability of liquid-vapor interfacial regions, interface thermophysics for polar and non-polar fluids, thin-film stability and rupture at the molecular level;
- Use of an opensource CFD package (OpenFOAM) with VOF and LS to simulate two-phase flows.
- Use of an in-house ALE-FEM code (Prof. Anjos) to simulate two-phase flows with an interface-fitting computational mesh.
- Use of an in-house MD code (Prof. Carey) to simulate the interface dynamics and phase change at the molecular level.
