In this thesis, computational multiscale methods for turbulent single and two-phase flows are considered. For large-eddy simulation of turbulent single-phase incompressible flow, a novel approach based on multifractal subgrid-scale modeling is developed. Two-phase flows, where the interface separating the two fluids appears as a discontinuity in the flow field, are tackled by an extendend finite element method. The combined approach is applied to large-eddy simulation of turbulent two-phase flow.
