Bubbling Fluidized Bed Behaviour for Biomass Gasification
(Doctoral dissertations at the University of South-Eastern Norway;35, Doctoral thesis, 2019-06-21)The need to cut down the high dependency on the fossil fuels requires sustainable alternative energy resources. Aside that the stock of fossil fuels is depreciable, the energy source also accounts for the major contribution ... -
Composite Distribution Solution for Minimizing Heat Loss in a Pyrolysis Reactor
(Journal article; Peer reviewed, 2011)The article presents a novel design for a distribution plate. The solution is suitable for a reactor vessel where a reactant gas needs to be maintained at a different temperature from the reaction chamber in order to avoid ... -
Computational modeling and experimental studies on fluidized bed regimes
(Master thesis, 2018)The fluidization technology has a wide range of applications from chemical synthesis to pneumatic transportation and circulation of species. Different process applications require different flow regimes and the type of ... -
Determination of onset of bubbling and slugging in a fluidized bed using a dual-plane electric capacitance tomography system
(Journal article; Peer reviewed, 2017)For a successful application of fluidized beds in chemical reactions and solids circulation, the boundary of regime of operation such as bubbling and slugging regimes, needs to be clearly defined. This study provides a ... -
Modelling and simulations of bubbling fluidized bed and entrained flow biomass gasification reactors
(Doctoral dissertations at the University of South-Eastern Norway;118, Doctoral thesis, 2022-02-24)The world needs sustainable energy solutions to replace fossil fuels. Climate change is the defining challenge of our time. New reports from the International Energy Agency (IEA, 2021)1 have developed a roadmap for max ... -
Simulation and parameter optimization of fluidized-bed and biomass gasification
(Doctoral dissertations at the University of South-Eastern Norway;92, Doctoral thesis, 2021-04-27)This thesis gives an insight to experimental studies and computational particle fluid dynamic (CPFD) simulations of fluidized bed and fluidized bed gasification reactors. CPFD models were validated against experimental ... -
Simulation of Simplified Model for Reaction Kinetics in Biomass Gasification
(Conference object; Peer reviewed, 2015-11-25)Due to complexity in interactions between solid particles and between particles and carrier fluid, modeling of biomass gasification kinetics has been shown to be very challenging. Some commercial packages such as Barracuda ...
