Direct Numerical Simulation and Modeling of Oxy-Fuel Combustion Processes (B03)

• Subject Area: Technical Thermodynamics
• Term: since 2013
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 215035359

Ignition, combustion, and pollutant formation of biomass particles will be studied by means of Direct Numerical Simulations (DNS) under laminar and turbulent conditions in air and oxy-fuel atmospheres. In this project, reduced-order models for the interactions between particles, chemistry, flow dynamics, and pollutant formation will be developed. DNS of a turbulent coflow jet and a realistic swirl burner configuration will be performed employing point-particle models that account for specific biomass characteristics. Model development will be guided by the optimal estimator concept, validated with DNS and experimental data and incorporated into the OxySim-129 modelling framework.
