Simulation and Modelling of Reacting Particles Relevant to Gas Turbine Engine Combustion

Abstract

A conditional moment closure model is proposed for reacting particles in turbulent nonpremixed combustion. The new model for particles differs significantly from the traditional uniform diffusivity gas-phase conditional moment closure model. The new features of the model and model effectiveness are examined against direct numerical simulation data for soot-like and droplet-like particles in turbulent nonpremixed combustion. The influence of differing particle sizes, types, and reactivity on the effectiveness of the model closure is examined in detail.
