Evaluation of advanced two-phase flow and combustion models for predictinglow emission combustors

The development of low-emission aero-engine combustors strongly depends on the availability, of accurate and efficient numerical models. The predictio n of the interaction between two-phase flow and chemical combustion is one of the major objectives of the simulation of combustor flows. In this paper , predictions of a swirl stabilized model combustor are compared to experim ental data. The computational method is based on tin Eulerian two-phase mod el in conjunction with an eddy dissipation (ED) and a presumed-shape-PDF (J PDF) combustion model. The combination of an Eulerian two-phase model with a JPDF combustion model is a novelty. It ii-as found to give good agreement to the experimental data.
