First industrial user for the CRC 287 Bulk-Reaction open-source DEM-CFD framework
thyssenkrupp Polysius is the first industrial user of the open-source DEM-CFD framework developed within the Corporate Research Center Center 287 Bulk-Reaction. The company is utilizing this DEM-CFD framework to simulate the flight and conversion behavior of refuse-derived fuels (RDF) in cement rotary kilns. These fuels have a size range of several centimeters and complex particle shapes. For such thermally thick particles, the DEM approach is well-suited to describe the physical and chemical intra-particle processes. When coupled with OpenFOAM as the CFD solver, this approach also enables the accurate simulation of the flight behavior of these complex-shaped particles.

Title: “Investigation on CO2 geological sequestration in the deccan volcanic province through multiphase flow and reactive transport simulations”
The seminar took place online via Zoom.
Industrial activity is the primary source of carbon emissions with a estimated 78% of total contribution. Carbon capture and sequestration (CCS) technology is one of the alternatives to reduce CO2 emissions, where the captured CO2 is transported to the facilities using various storage techniques. Geologic carbon sequestration (GCS) is one such technique, where deep geological subsurface formation is used as permanent storage facility. Based on available geological, petrophysical, and geochemical properties, the Deccan volcanic province is one of India’s largest sinks for geological CO2 sequestration. Approximately 5,000,000 km2 of India is covered with Deccan basalt. The fate of injected CO2 in the geological formations follow various physical trappings and chemical transformations which are classified as structural, residual, solubility, and mineral trapping mechanisms.
The current research investigates the possible implementation of CO2 geological sequestration in the Deccan volcanic province. The numerical simulation analysis is carried out to analyse the influences of specific sequestration parameters like the injection rate and injection point; and geological parameters like top surface morphology, petrophysical properties variation, and geological features like stairsteps traps and anticline on the CO2 plume migration in the subsurface formation domain. The effect of these sequestration and geological parameter variations is analysed on the trapping mechanism, sweeping efficiency and structural integrity over a geological time scale for the considered subsurface synthetic domain. The multiphase, multicomponent reactive transport modelling technique is utilized to conduct this analysis. The outcome of this research has shown insight into the potential implementation of CCS and a future estimate of CO2 migration and CO2 entrapment. Further, provide the impacts of sequestration and geological parameters over a geological time scale. Future studies will focus on caprock leakage analysis, leakage implications on different entrapment mechanisms and machine learning approaches to predict the entrapment percentage, leakage, and structural integrity research for long geological time scales.
Keywords: Carbon Capture and Storage, Geologic Carbon Sequestration, Trapping mechanisms, Sequestration parameters, Geological parameters, Reactive transport modelling.

Code and Data Sprint in Magdeburg
Nov., 2023
The Code and Data sprint was a two day event and took place in Magdeburg.
This CDC continued the first CDC in Berlin and further actions were undertaken to develop RDM in the CRC287. Data Management plans of the projects were updated by the doctoral researchers and example data sets were prepared. Further in-depth diving into the central data management platform Confluence was conducted. Group discussions with experts helped to answer urgent questions regarding RDM. In addition, the projects conducted several steps of internal review process to optimize the preparation and documentation of their datasets.

The CRC/TR 287 has organized a workshop at the 11th European Combustion Meeting (ECM) 2023:
Discrete kinetic methods for combustion simulation: Fundamentals and Practice
It is organized by Dr. Seyed Ali Hosseini.
Development of efficient and physically sound new algorithms adapted to the constantly evolving high performance hardware architecture is of the utmost importance, especially in computation-intensive applications such as combustion. Over the past decades the lattice Boltzmann method (LBM) and other kinetic- theory-based numerical approaches have proven themselves to be very efficient alternatives to classical Navier-Stokes-based solvers in the incompressible regime both on CPU- and GPU-based platforms. The rapid growth of industrial solvers based on the LBM is a clear testament to computational advantages of the latter. This success in the incompressible regime prompted the community at large to extend the scheme to compressible flows, and eventually combustion simulations. The past 5-10 years have witnessed a rapidly growing interest in the development of discrete kinetic methods for combustion simulations in both low and high Mach regimes.
The aim of this workshop, held in the context of the 2023 edition of the European Combustion Meeting in Rouen (France) is to gather experts in the area of the kinetic theory of gases and discrete methods based on the latter to discuss challenges and opportunities, recent progress and future of discrete kinetic methods for the simulation of reacting flows. The half day workshop included talks by experts in the field followed by short presentations from doctoral students and post-doctoral researchers illustrating most recent applications of discrete kinetic methods.
We warmly invite all interested parties to take part in this first edition of the workshop and, for those active in that area of research, submit abstracts to present their most recent progress. Accepted abstracts led to oral presentations of 5-10~mins in the last section of the workshop. Should the number of abstract be large, the possibility for poster presentation was also considered.
