During a postulated loss-of-coolant-accident (LOCA) in a pressurized water reactor (PWR) it is of vital importance that the reactor core remains properly cooled. The emergency core cooling system (ECCS) in German PWRs compensates the loss of coolant with injection of additional coolant into the cold legs as well as into the hot legs. While the cool...
The Forschungszentrum Rossendorf (FZR) e. V. is constructing a new large-scale test facility, TOPFLOW, for thermalhydraulic single effect tests. The acronym stands for transient two phase flow test facility. It will mainly be used for the investigation of generic and applied steady state and transient two phase flow phenomena and the development an...
Objective of the project is the prognosis and optimization of the production from Tight-Gas reservoirs and the identification of damaging mechanisms in the system well-fracture-reservoir. The productivity of fractured wells in Tight-Gas formations remains frequently behind the forecasts. Therefore, this research work focuses on the following: (i) t...
An asymptotic analysis for magnetohydrodynamic flows between perfectly conducting concentric cylindrical shells has been performed. The flow in the model geometry exhibits all features which had been discovered in the past for the case of differentially rotating spherical shells considered in the context of geophysical analyses. For strong magnetic...
