In this thesis a numerical framework for the Eulerian large-eddy simulation (LES) of liquid-fuel injection and turbulent mixing under high pressures is developed. The framework is based on cubic equations of state, thermodynamic stability analysis, and vapor-liquid equilibrium calculations. Coexistence of supercritical states and multi-component subcritical two-phase states are represented by means of a homogeneous mixture approach. Well-resolved LES results are presented for reference experiments relevant for liquid rocket engines and internal combustion engines.
