Abstract

We have developed a thermodynamically consistent and tuning-parameter-free two-phase model for Eulerian large-eddy simulations (LES) of liquid-fuel injection and mixing at high pressure. The model is based on cubic equations of state and vaporliquid equilibrium calculations. It can represent the coexistence of supercritical states and multi-component subcritical two-phase states via a homogeneous mixture approach without any semiempirical break-up and evaporation models. Computational results for liquid-fuel injection at transcritical operating conditions are found to agree very well with available experimental data for the ECN Spray A.
