Experimental study and SEM-EDS analysis of agglomerates from gasification of biomass in fluidized beds
(Peer reviewed; Journal article, 2022)Fluidized bed gasification is an attractive conversion technology for biomass. However, processing biomass in fluidized beds suffers from ash related problems. In this work, bed agglomeration of wood pellets and grass ... -
Experimental study of agglomeration of grass pellets in fluidized bed gasification
(Chapter; Peer reviewed, 2020)The agglomeration tendency during gasification of grass pellets in a bubbling fluidized bed reactor was studied. Particle agglomeration occurs as a consequence of interactions between the bed particles and the biomass ash ... -
Experimental Study of Gas Explosions in Hydrogen Sulfide-Natural Gas-Air Mixtures
(Journal article; Peer reviewed, 2014-08-21)An experimental study of turbulent combustion of hydrogen sulfide (H2S) and natural gas was performed to provide reference data for verification of CFD codes and direct comparison. Hydrogen sulfide is present in most crude ... -
Experimental study of primary atomization characteristics of sonic air-assist atomizers
(Journal article; Peer reviewed, 2021)The present study compares two twin-fluid atomizer concepts based on the airflow (shock waves) pattern obtained through shadowgraph imaging for atomization of water with a low air/water pressure supply. The research work ... -
Experimental Study of the Initial Flame Propagation of Premixed H2-air Explosion in a Channel
(Conference object; Peer reviewed, 2009-07)This paper presents results from experiments on flame propagation in inhomogeneous and homogeneous hydrogen-air mixtures at 1 atm in a channel. The objective of the present work is to study the ininitial phase of the flame ... -
Experimental study of thermal and catalytic pyrolysis of plastic waste components
(Journal article; Peer reviewed, 2018)Thermal and catalytic pyrolysis of virgin low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP) and mixtures of LDPE/PP were carried out in a 200 mL laboratory scale batch reactor at 460 °C ... -
Experiments and computational particle fluid dynamics simulations of biomass gasification in an air-blown fluidized bed gasifier
(Journal article; Peer reviewed, 2020)Experiments were performed in a pilot-scale bubbling fluidized bed gasification reactor with air as a fluidizing agent. Birch wood chips and sand particles were used as biomass and bed materials. Average molar product gas ... -
Experiments with flame propagation in a channel with one obstacle and premixed H2-air
(Conference object; Peer reviewed, 2009-07)This abstract presents experimental results of flame propagation in a square channel with a single obstacle. The background for the experimental study was to investigate how a flame propagated when and after the flame ... -
Explosion characteristics for Li-ion battery electrolytes at elevated temperatures
(Peer reviewed; Journal article, 2019)Li-ion batteries are used in electronic devices and electric cars, yet they create safety concerns due to the possibility of the release of combustible materials. The electrolyte, one of the main components in a Li-ion ... -
Firefly optimization and mathematical modeling of a vehicle crash test based on single-mass
(Journal article; Peer reviewed, 2014)In this paper mathematical modeling of a vehicle crash test based on a single-mass is studied. The model under consideration consists of a single-mass coupled with a spring and/or a damper. The parameters for the spring ... -
Flow behavior in an agglomerated fluidized bed gasifier
(Peer reviewed; Journal article, 2019)The global energy demand has increased over the last decades and the need for utilization of energy produced from sustainable sources is stressed. Fluidized bed gasification of biomass is a thermochemical conversion process ... -
