Multi-scale Modeling of Topology Change in Multiphase Flow Simulations

Explore new developments in the geometric volume of fluid method for tracking sub-grid scale interfacial features in multiphase flow simulations. Learn how ligaments and sheets can be accurately represented independently of mesh resolution while maintaining exact conservation, computational efficiency, and compatibility with finite-volume-based flow solvers. Discover the implications of these strategies on topology change and the need for explicit physics-based models. Examine various approaches to modeling the break-up of thin liquid films, a common feature in aerodynamic liquid atomization. This 56-minute conference talk by Prof. Olivier Desjardins from MICDE University of Michigan delves into multi-scale modeling techniques for topology change in multiphase flow simulations.
