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 ...

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 ...

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 ...

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- ...

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 ...

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 ...
