The production of oil is challenging in fractured reservoirs due to the large transmissibility contrast between matrix and fracture, and primary recovery is often low. The recovery efficiency depends on the relationship ...

This Master thesis describes an experimental study aimed at determining the minimum ignition energy (MIE) of premixed propane/air mixtures. Two fundamentally different circuits have been employed for creating the sparks ...

The purpose of this thesis was to provide a high level software framework for detecting large problems with the ATLAS detector at the LHC and estimate the jet resolution from the f irst data. The result was the program ...

The working of solid oxide fuel cells (SOFCs) involve fluid dynamics, chemical reactions and electrochemical processes. These phenomena happen simultaneously in complex and sophisticated structures of the SOFC main ...

Ulike metoder for økt oljeutvinning (EOR, eng. Enhanced Oil Recovery) har blitt utviklet og anvendt for å forbedre effektiviteten av konvensjonell vannflømming. Hensikten med EOR er å bedre den mikroskopiske fortrengnin ...

Ved høye trykk og lave temperaturer kan vannmolekyler danne strukturelle bur rundt et gjestemolekyl. Denne substansen er da i fast form og kalles hydrat. I naturlig forekomst av gasshydrat er metan det vanligste gjestemolekylet. ...

Dispersion of accumulated layers of combustible dust by turbulent flow or shock waves ahead of a propagating flame can play an important role for explosion propagation in coal mines. In 1924, Greenwald and Wheeler ...

Dispersion of accumulated layers of combustible dust by turbulent flow or shock waves ahead of the propagating flame may sustain explosion propagation in coal mine galleries and other industrial facilities. The mechanisms ...
