Abstract

This project focuses on the design, development, implementation and optimization of methods, algorithms and software for large scale simulations of free surface and multi-phase flows based on the generalized lattice Boltzmann method (GLBM). Parallel solvers and cache optimized algorithms have been developed to simulate multi-phase and turbulent transient flows in complex three-dimensional geometries. For the simulation of free surface problems where the fluid domain changes with time adaptive methods have been developed. The first subproject is concerned with the simulation of complex turbulent flows around building structures. The second subproject is concerned with the accurate and reliable prediction of transport of contaminants and nutrients in porous media (soils) on different scales (DFG-Project FIMOTUM, First principle based transport in unsaturated media). The third subproject is concerned with the simulation of free surface flows for different engineering applications.
