Research Topics and Group Structure
The main subject of the group Interphase Phenomena (IPP) is understanding and modeling the interaction between individual particles and surrounding gas including chemical reactions on the interface between two phases. In particular, coal (wood) gasification (synthetic gas production) is considered as background processes under investigation. The project is a self-standing one which, however, greatly benefits from a close interaction with the Groups "Reacting Flow Systems" and "Multiphase Systems".
The global objective of the group is the development of numerical and empirical-subgrid models devoted to the modeling of chemical-reacting particles in multi-phase systems including solid-gas, solid-liquid and liquid-gas phases. To achieve this aim, the project is based on an approach which combines numerical simulations of phase-change phenomena on the meso- and the microscale. The microsimulations pursue two main goals. The first is the prediction of the drag force and the heat and the mass transfer coefficients, which are needed in the project "Reacting Flow Systems" for the macroscale simulations of chemical reacting flow. The second is the simulation of the evolution of the shape of a coal particle during its partial oxidation including the prediction of the time of dissolution of particles and their porous structure.
The long-term vision is a contribution to a complex multi-scale model of an entrained flow gasifier and a fluidized bed gasifier in order to optimize the processes and to enhance the efficiency of synthetic gas production and iron making.
