The long term objective of the Research Group "Reacting Flow Systems" is the comprehensive modelling and simulation of existing and future industrial high-temperature conversion processes. The fluid flow in these reactors is usually highly turbulent (with and without swirl) with temperatures larger than 2000°C and pressures of up to 100 bar. In addition, for coal gasification the flow is laden with particles and both the loading and the particle size distribution varies significantly within the reaction chamber. Major research areas for the group are the modelling and simulation of the turbulent flow field and the homogeneous chemical on the one hand as well as the chemistry-turbulence interaction on the other hand. A special focus is placed on the latter, for which a multi-scale model, which is similar to the flamelet model for combustion processes, is developed for gasification processes. The newly developed submodels of the group "Interphase Phenomena", e.g. drag coefficients and heat transfer coefficients in particle clusters, as well as the new data from the group "Multiphase Systems", e.g. for fusion temperatures, viscosities and the surface tension, are combined by the group "Reacting Flow Systems" and the complete model will be used for the simulation of the complete reaction chamber. The focus during the first phase of Virtuhcon is placed on the description of reference processes, for which experimental data for model validation is available or can be obtained together with the initial institutes. These virtual reference processes are the basis for the investigation, development and optimization for future virtual prototype processes.
