In der vorliegenden Arbeit wird ein mathematisches Modell entwickelt um magnetohydrodynamische Strömungen in instationäre und inhomogene Magnetfelder zu beschreiben. Das Modell wird in das finite-Volumen basierende CFD-Programm OpenFOAM implementiert und an typischen Problemstellungen der Magnetohydrodynamik verifiziert und validiert. Mit dem entwickelten Algorithmus wird ein Frequenzdurchflussmessgerät numerisch modelliert und erfolgreich simuliert. In this work, I develop a numerical model for magnetohydrodynamic flows in unsteady an inhomogeneous flow. The model is implemented in the finite-volume based CFD-code OpenFOAM. Some verification and validation tests are made on several standard problems of magnetohydrodynamics. Finally I successful modelled an electromagnetic flowmeter with the code.

A survey of the German population addressed attitudes towards scenarios of big data practices, i.e. price discrimination in retail, credit scoring, differentiations in health insurance and in employment, with features of using internet data, automated decision-making, and selling of data. The study analysed behavioural adaptations, protection measures, relations to demographics, personal value orientations, knowledge about computers, and attitudes about privacy and data protection.

Das F+E-Vorhaben INOVUM des Ministeriums für Umwelt, Klima und Energiewirtschaft Baden-Württemberg setzt auf eine breite Kooperation mit Partnern aus Verwaltung, Wissenschaft und Wirtschaft zum gemeinsamen Ausbau der behördlichen Umweltinformationssysteme. Schwerpunkte der Projektphase INOVUM II waren u.a. Aspekte der Digitalisierungsstrategie des Landes Baden-Württemberg, Weiterentwicklung servicebasierter Umweltportale, mobile Anwendungen, Big-Data-Technologie und Aufbau eines Sensornetzwerks. The R & D project INOVUM of the Ministry for the Environment, Climate and Energy Baden-Württemberg relies on a wide cooperation with partners from government, science and industry to jointly develop governmental environmental information systems. In the focus of the project phase INOVUM II were, e.g. aspects of the digitalisation strategy of Baden-Württemberg, enhancements of service-based environmental portals, mobile applications, big data technologies and the design of a sensor network.

The Proceedings of the Second Annual Workshop of the Collaborative Project CEBAMA addresses key scientific questions related to the use of cement-based materials in nuclear waste disposal applications. Progress beyond the state-of-the-art is achieved by providing basic knowledge, new experimental data, improved modeling and arguments for the Nuclear Waste Disposal Safety Case. CEBAMA is funded by the European Commission under the Horizon 2020 frame of EURATOM.

Sodium is used in concentrating solar power systems due to its excellent heat transfer properties and large operating temperature range. In a systematic evaluation of a range of thermal energy storage systems a packed-bed thermocline storage with filler material has been identified as a promising storage configuration. Numerical investigations demonstrate that such a storage system can be successfully charged and discharged with sodium.

Das BMWi-Verbundprojekt setzte sich aus mehreren Benchmark-Übungen zusammen. Die Problemstellung des Benchmarks entwickelte sich von der Verifikation der Rechenprogramme und Stoffmodelle bis zur Bewertung der Prognoserechnungen durch Vergleich mit den Ergebnissen thermomechanischer in situ Versuche. Das Projekt diente einer Einschätzung der Stoffgesetzfähigkeiten im Hinblick auf deren Einsatz bei der praktischen Anwendung der Berechnung von Endlagern für wärmeentwickelnde Abfälle im Steinsalz. Between October 2010 and July 2016, the German Federal Ministry for Economic Affairs and Energy (German abbreviation BMWi) has funded a joint project within its research program “Improvement of tools for the safety assessment of underground repositories”. The aim of benchmark calculations was to check the ability of the involved models to describe the temperature influence on deformation, the damage and dilatancy reduction and healing of rock salt

The EURATOM FP7 Collaborative Project “Fast / Instant Release of Safety Relevant Radionuclides from Spent Nuclear Fuel (CP FIRST-Nuclides)” improved significantly the understanding of the mobilization of dose-dominating radionuclides from high burnup spent nuclear UO₂ fuels. The data are decisive for safety analysis for deep geological nuclear waste repositories.
