Group CFD-Modeling

ProVirtThe tasks of the “CFD Modeling of High-Temperature Processes“ division focus on the modeling of high-temperature processes across the entire spectrum ranging from chemically reacting particles to the complete reactor. One key aspect is the development of models and strategies for the simulation of high-temperature reactors such as fixed-bed, fluidized-bed, and entrained-flow in metallurgy and chemical engineering. Fundamental research on subsystems is incorporated into the development of advanced sub-models. These sub-models are then integrated into reactor models for an improved simulation of reacting fluid-solid systems. Based on insights gained through such advanced modeling, optimization strategies can be developed for an accelerated adaption of existing technologies as well as for the development of new technologies.

Research Group Multiphase Models

The research group Multiphase Models focuses on the detailed modelling of complex thermo-chemical, multiphase processes for metallurgical and chemical processes. High resolution numerical studies of different sections in complex technological systems facilitate the discovery of new correlations and are the basis for advanced models in the fields of phase change and conversion processes. The cooperation with the research group Material and Process Analysis furthermore supports the validation against reference data. The new and/or improved models forms the basis for activities by the research group Process Virtualization. This group focuses on the modeling of entire technological processes.

Research Group Material and Process Analysis

The experimental work of the research group Material and Process Analysis forms the basis for advanced and realistic process virtualization. This comprises the measurement of material properties for different phases and the characterization of interphase phenomena. An innovative model-assisted approach supports an estimation of absolute material properties and process data from effective quantities which are measured experimentally. For this, the research group works closely with the research groups Process Virtualization and Multiphase Models and benefits from their modeling expertise. Another research focus is the compilation of process data from our large-scale reference facilities at IEC and INEMET, where in particular in-situ measurement techniques are being applied. In addition to facilitating a deeper understanding of the investigated processes, the datasets will also be used to support the validation of numerical models.
