In this project, the GPU enabled spectral element code Neko will be extended to computational fluid dynamics simulations with moving components and simulations of multi-phase flows. Initial prototyping will be carried out as well scaling tests. In particular, new features will be developed and tested using this allocation. The features needed for moving geometries will be based on the Schwarz alternating method and be applied to simulations of the rotor stator interactions in low-pressure turbines. In addition, post-processing and in-situ tools for data-driven analysis and visualization of the simulation results will be incorporated into Neko. Furthermore, an novel approach using the phase-field method for multi-phase flows will be added to Neko. This will enable large-scale simulations with applications in additive manufacturing, understanding bubble formation and also expand into enabling simulations of more complex fluids. The developments in this compute project will enable detailed simulations of complex flow phenomena at a large scale and in more complex geometries than previously thought possible.
