Validation of coupled neutronic / thermal-hydraulic codes for VVER reactors Final report
...
In recent years, the simulation methods for the safety analysis of nuclear power plants have been continuously improved to perform realistic calculations. Therefore in VALCO work package 2 (WP 2), the usual application of coupled neutron-kinetic / thermal-hydraulic codes to VVER has been supplemented by systematic uncertainty and sensitivity analys...
Time and spatial turbulence development in a Ludwieg tube and its influence on the transition on airfoil modells / Zeitl...
Flow quality measurements were conducted in the cryogenic Ludwieg-tube (KRG) where time and spatial development of single fluctuation quantities were investigated. Here the total and static pressure, total temperature and mass flow were recorded in the test section as well as in the storage tube of the KRG. The dependence of the flow quality on the...

Comparison of wake-vortex parameters measured by 2 #mu#m pulsed and 10 #mu#m cw lidars
Field trials carried out at Tarbes airfield in the summer 2002 offered the unique possibility to compare the results of simultaneous wake-vortex measurements by the 2 #mu#m pulsed doppler lidar from DLR and the 10 #mu#m cw doppler lidars from ONERA and QuinetiQ. Good agreement could be found for both the vortex-core position and the vortex circulat...

Climatology and internal variability in a 1000-year control simulation with the coupled climate model ECHO-G
The climatology and internal variability in a 1000-year control simulation of the coupled atmosphere-ocean global climate model ECHO-G are analyzed and compared with observations and other coupled climate model simulations. ECHO-G requires annual mean flux corrections for heat and freshwater in order to simulate no climate drift for 1000 years, but...
An upgraded estimate of the radiative forcing of cryoplane contrails
The radiative forcing of contrails is quantified for a hypothetical fleet of cryoplanes in comparison with a conventional aircraft fleet. The differences in bulk optical properties between conventional and cryoplane contrails are determined by numerical simulations, under several ambient conditions, of the microphysical evolution of conventional an...
