Some Aspects of Gas Turbine Fuel Preparation and Turbomachinery Response to LCV Fuels

Eriksson, Pontus

This thesis gives some background information on environmental issues as the scientific community at large currently sees it. It tries to relate the plethora of current combustion technologies which may be used in gas turbines to those issues. Some basic principles on combustion design are given. Di...

Rôle des diagnostics optiques en temps réel dans le contrôle d'une colonne d'extraction liquide-liquide type pulsée - comparaison expérience / modèle

Syll, Ousmane

La conception d’une colonne d’extraction liquide-liquide repose sur le mécanisme de transfert d’énergie conduisant à une fragmentation de la phase légère en gouttelettes permettant le transfert de matière avec la phase lourde. Toutefois ce mécanisme présente de façon récurrente à chaque plateau une ...

GPS radio occultation with CHAMP and SAC-C: global monitoring of thermal tropopause parameters

Schmidt, T.; Heise, S.; Wickert, J.; Beyerle, G.; Reigber, C.

In this study the global lapse-rate tropopause (LRT) pressure, temperature, potential temperature, and sharpness are discussed based on Global Positioning System (GPS) radio occultations (RO) from the German CHAMP (CHAllenging Minisatellite Payload) and the U.S.-Argentinian SAC-C (Satelite de Aplica...

Exploitation des nouvelles capacités d'observation de la terre pour évaluer le rayonnement solaire incident au sol. Assessment of solar surface radiation using new earth observation capabilities.

Oumbe Ndeffotsing, Armel Bertrand

Peu de stations au sol mesurent l'éclairement et des méthodes ont été développées pour l'évaluer à partir d'images prises par des satellites géostationnaires ou en orbite polaire. Dans les méthodes actuelles, dites inverses, le signal perçu par le satellite est inversé pour dériver le rayonnement au...

Deep convective injection of boundary layer air into the lowermost stratosphere at midlatitudes

Fischer, H.; De Reus, M.; Traub, M.; Williams, J.; Lelieveld, J.; De Gouw, J.; Warneke, C.; Schlager, H.; Minikin, A.

On 22 August 2001 a measurement flight was performed with the German research aircraft FALCON from Sardinia to Crete as part of the Mediterranean Oxidant Study (MINOS). Cruising at 8.2 km, the aircraft was forced to climb to 11.2 km over the southern tip of Italy to stay clear of the anvil of a larg...
