An experimental and computational study of flow behaviour in bubbling fluidized beds
(Doctoral theses at NTNU;2005:70, Doctoral thesis; Peer reviewed, 2005)
Experimental and computational studies of bubble behaviour in gas/solid fluidized beds have been performed. Bubble behaviour depends on particle density, particle size and size distribution and emphasis is given to study ...
The impact of staged combustion on the operation of a precalciner cement kiln
(Doctoral theses at NTNU;1999:89, Doctoral thesis; Peer reviewed, 1999)
In this thesis, the impact of staged combustion on the operation of a precalciner cement kiln, is considered. Mathematical modelling and full-scale experiments at the Norcem cement works in Brevik, Norway, is the basis for ...
Experimental Study of Deflagration to Detonation Transition in Hydrogen-Air Mixtures
(Doctoral dissertations at TUC;2015:1, Doctoral thesis; Peer reviewed, 2015-04-29)
Gas explosions in a square channel have been investigated with a main focus on the deflagration to detonation transition (DDT). The gas mixtures were hydrogen and air at different concentrations. This work have been motivated ...
Gas explosions in process pipes
(Doctoral theses at NTNU;2004:79, Doctoral thesis; Peer reviewed, 2004)
In this thesis, gas explosions inside pipes are considered. Laboratory experiments and numerical simulations are the basis of the thesis. The target of the work was to study gas explosions in pipes and to develop numer- ...
An Experimental and Theoretical Study of Dense Fluidized Bed Fluid Dynamics
(Doctoral dissertations at TUC;2012:3, Doctoral thesis; Peer reviewed, 2012-05-31)
The papers presented in the present study aim to elucidate the complex fluid dynamic phenomena in a cold dense phase fluidized bed reactor. Theoretical and experimental studies were conducted with this aim and several ...
Anaerobic degradation of industrial carbon capture reclaimer MEA waste
(Doctoral dissertations at TUC;2014:5, Doctoral thesis; Peer reviewed, 2014-04-04)
Global warming and its impacts are serious and challenging international problems (Vitousek, 1994). Increasing fossil fuel consumption results in rising atmospheric greenhouse gas levels which enhances global warming ...
