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.

Workshop on “Gender appropriate candidate assessment” in Magdeburg by Dr. Steffi Nothnagel (Diversity Consulting)
The workshop addressed gender appropriate candidate assessment during recruitment processes. It presented strategies and good-practice examples on how to avoid gender bias within the recruiting process based on equal treatment of all applicants. Established approaches at both universities were discussed and evaluated with regard to opportunities for improvement.

Title: “Machine Learning for Thermochemistry Tabulation”
The seminar will take place in lecture theatre H2 (room number A021) on the ground floor of Building 22A in Magdeburg. You may also participate electronically.
Several methods for the computation of reacting flows involve real-time integration of chemical kinetics. These methods include transported probability density function (PDF) methods, direct numerical simulation (DNS), conditional moment closure (CMC), unsteady flamelet, multiple mapping closure (MMC), thickened flame model, linear eddy model (LEM), partially stirred reactor (PaSR, as in OpenFOAM) and laminar flame computation. The need for direct integration of kinetics often renders large-scale simulations with these methods prohibitively expensive. This issue can be overcome by tabulation, which is the pre-computing and storage of computationally expensive operations. Tabulation raises further issues, however, such as the anticipation and coverage of the states to be encountered during simulation and the avoidance of excessive memory requirements.
The present seminar described a tabulation approach with artificial neural networks (ANNs), which are a class of machine learning models that can be employed for function approximation. After a review of the first-generation ANN tabulation methods, we discussed recent developments that enable the generation of data-driven models able of accommodating a wide range of reacting flows, including laminar flamelets and premixed flames, turbulent non-premixed and premixed flames and flames with fuel blends and energy losses. The main elements of the methodology were discussed, together with an explanation of how they lead to enhanced generalisation, accuracy and error control.
