Bridge over Troubled Water - veien fra akademia til industri - og tilbake
(The Michelsen Centre or Industrial Measurement Science and Technology, 2010-04-15)
Reciprocity calibration method for ultrasonic piezoelectric transducers in air
(The University of Bergen, 2013-06-17)
The conventional three-transducer reciprocity calibration method for use in gas at ambient pressure and temperature is studied. Modifications are introduced, introducing correction factors for absorption in air, diffraction ...
Two particle correlation effects from rotation and instabilities in heavy ion collisions
(The University of Bergen, 2013-05-18)
Two particle correlations are studied in the reaction plane of peripheral relativistic heavy ion reactions where the initial state has substantial angular momentum. The earlier predicted rotation effect and Kelvin Helmholtz ...
Modelling of vented dust explosions – empirical foundation and prospects for future validation of CFD codes
(Institution of Chemical Engineers (IChemE), 2008)
Explosion venting is the most frequently used method for mitigating the effects from accidental dust explosions in the process industry. Optimal design of vent systems and credible execution of risk assessments in powder ...
Geo-modeling and fluid flow simulation in paleokarst reservoirs
(The University of Bergen, 2015-06-30)
This master thesis focuses on modeling and simulation of fluid flow in collapsed paleocave systems, also known as paleokarst. Petroleum reservoirs all around the world exhibit karst structures. The latest ones on the ...
Simulation of prompt gamma production in particle therapy and beam trajectory imaging
(The University of Bergen, 2015-06-01)
In cancer oncology, using of Mega electron Volt (MeV) bremsstrahlung photons has been clinically practised on cancer patients since photons can deliver a significant dose to tumour volumes when projected into the body in ...
Combustion of Gas in Closed, Interconnected Vessels: Pressure Piling
(The University of Bergen, 2004)
This thesis is the documentation of a study of gas explosions in closed, interconnected vessels. Explosions within such vessels is strongly affected by the characteristics of the geometry, and can, under given conditions, ...
Possibilities, limitations, and the way ahead for dust explosion modelling
(Institution of Chemical Engineers (IChemE), 2006)
The purpose of the present paper is threefold. First, a brief review of modelling, main results, and preliminary conclusions from the DESC project are presented; current capabilities and limitations of the DESC code are ...
Transport and storage of CO2 in natural gas hydrate reservoirs
Storage of CO2 in natural gas hydrate reservoirs may offer stable long term deposition of a greenhouse gas while benefiting from methane production, without requiring heat. By exposing hydrate to a thermodynamically preferred ...
Reduction of noise in seismic hydrophone arrays modelling of breathing waves and adaptive noise cancelling
(The University of Bergen, 1993-04)
