In the frame of supporting BMU regarding generic questions concerning probabilistic safety analyses for nuclear power plants as well as regarding evaluation of nuclear specific standards and guidelines the significant contributions to damage states resulting from plant internal and external hazards had to be estimated for a German Konvoi type PWR r...
Development, implementation and verification of a reduced hydrogen-air chemistry model for the COM3D computer code
Das grundlegende Ziel dieser Arbeit war die Entwicklung eines schnellen und dabei hinreichend genauen chemischen Modells fuer die Nutzung in dreidimensionalen CFD-Programmen. Zu diesem Zweck wurde eine neue Herangehensweise zur Vereinfachung detaillierter Schemata vorgeschlagen. Die wesentliche Annahme dieser Methode sind gleiche Konzentrationen, V...
Prevention of large-surface methane emissions at the surface of abandoned mines as a function of top rock characteristic...
The project investigated protective measures against methane emissions as well as options for utilization of the methane in power supply. The investigations were carried out in the southern Ruhr district near Bochum and Dortmund and in the eastern Ruhr district near Hamm. Geological, tectonic, hydrogeological and geothermal factors were taken into ...
CFD software optimization and non-nuclear application HGF-H2 project: Part 2 / CFD Software Optimierung und nicht-nuklea...
This report describes the R and D work performed within the scope of EC/HGF project activities concerning the numerical simulation of reacting flow in complex geometries. The aim is the refinement of numerical methods used in computational fluid dynamics (CFD) by introducing high-performance computations (HPC) to analyse explosion processes in tech...
