Detailed Chemistry Prediction of Time-Dependent Turbulent-Combustion within a Gasoil-Fueled Rapid-Mix Burner-Combustor System

The paper, in its first part, reports synthetically about the latest conceptual and numerical developments implemented into the CRFD (Computational Reactive Fluid Dynamics) parallel/clusterized solver NastComb, discussing in particular its most recently programmed detailed-chemistry mechanism. This scheme adopts a PASR (Partially Stirred Reactor) approach together with an SGI (Sub Grid Interaction) model in order to represent the turbulence-chemistry cross-influences. In the second part, preliminary results are given and discussed of the application of the code to an experimental, gasoil-fueled, LRPM (Liquid-fuel Rapid Pre-Mix) gas-turbine burner, characterized by ultra-low emissions. Comparisons with measured temperature data turn out quite positive, whilst the detailed chemistry provision allows to go deep into the mechanisms of radical and pollutant species formation.
