Global scale gravity wave observations and analysis with the ESA Earth Explorer 11 candidate CAIRT
EGU General Assembly 2023, WienWien, Austria, 23 Apr 2023 - 28 Apr 20232023-04-232023-04-28
The ESA Earth Explorer 11 Candidate CAIRT is a prime candidate for reliably observing gravity wave (GW) activity throughout the middle atmosphere up to the MLT region from about 15 km to 90 km altitude. A horizontally panning spectrometer with limb viewing geometry allows for the measurement of 3-dimensional temperature fields with high vertical resolution that can be used to quantify the global GW distributions and spectra as well as individual GW events. [...]

Numerical Simulation of Hydrogen Spread in an Industrial Building Using containmentFoam
Aachen Hydrogen Colloquium, AachenAachen, Germany, 18 Apr 2023 - 19 Apr 20232023-04-182023-04-19
As the applications of Hydrogen as a replacement for fossil fuels and energy storage increases, more safety issues should be studied. Due to its small low value of the lower flammability limit (LFL), Hydrogen safety hazards due to leakage, especially in closed buildings, should be studied to avoid any damage that can result from the detonation of Hydrogen after mixing with air. [...]

Analyses of Jet-Buoyant Flow in a Multi-Compartment Containment using an Open-Source Solver
20th International Topical Meeting on Nuclear Reactor Thermal Hydraulics (NURETH-20), WashingtonWashington, USA, 20 Jan 2023 - 25 Jan 20232023-01-202023-01-25
Hydrogen mixing and distribution in a nuclear power plant containment during a postulated severeaccident is a phenomenon with high safety relevance for current and advanced LWR. The OECD/NEASETHproject was carried out to generate the experimental data on basic containment phenomena with therequired instrumentation to assess CFD and LP codes.In this paper, we analyzed the PANDA Test 16 of the OECD/NEA-SETH project by usingcontainmentFOAM which is a tailored open-source CFD code package for containment analysisdeveloped at Forschungszentrum Jülich (Germany) based on OpenFOAM® v9 [...]

Experiments on the impact of carbon monoxide on the efficiency of catalysts used for hydrogen mitigation in the late phase of a severe accident
20th International Topical Meeting on Nuclear Reactor Thermal Hydraulics (NURETH-20), WashingtonWashington, USA, 20 Aug 2023 - 25 Aug 20232023-08-202023-08-25
The molten core-concrete interaction in the ex-vessel phase of a severe accident in a light water reactor is the source of significant amounts of carbon monoxide among other gaseous products. The European project AMHYCO addresses open issues related to the understanding of the impact of carbon monoxide on phenomena occurring in the late accident phase [...]

The CAIRT earth explorer 11 mission: a way towards global gravity wave momentum budgets
EGU General Assembly 2023, WienWien, Austria, 23 Apr 2023 - 28 Apr 20232023-04-232023-04-28 [10.5194/egusphere-egu23-12273]
Retrieving global observations of gravity waves (GW) from recent satellite missions is challenging. Nadir viewing satellites such as AIRS provide directional momentum fluxes, but lack fine vertical resolution and hence observe only those GW with exceptionally high intrinsic phase speed. [...]

Gravity waves (GWs) transport energy within the atmosphere both in vertical and horizontal direction. While the former is considered in climate models via parameterizations, the latter is often not modeled in most long time simulations. [...]
