Biofilm in Moving Bed Biofilm Process for Wastewater Treatment
(Chapter, 2019)A brief introduction of the long history of biofilm-based wastewater treatment is given together with basics of biofilm behavior and mechanisms in removal and transformation of pollutants. Moving bed biofilm reactor (MBBR) ... -
Combined calcination and CO2 capture in cement clinker production by use of electrical energy
(Chapter, 2019)The technical feasibility of electrifying the calcination process in a precalciner cement kiln system was assessed by studying different electrification concepts. Resistance-based heating was selected as it equires no CO2 ... -
Comparison of OpenFoam and ANSYS Fluent. Compitational Fluid Dynamic Simulation of Gas-Gas Single Phase Mixing with and without Static Mixer
(Chapter; Peer reviewed, 2016)Gas-gas single phase mixing were numerically evaluated with static mixer and without static mixer using OpenFoam and ANSYS Fluent codes. The main goal was the gas-gas mixing simulation comparison between ANSYS Fluent and ... -
CPFD simulation of a fixed bed gasification reactor
(Chapter; Peer reviewed, 2020)Biomass gasification is regarded as one of the most promising energy recovery technologies. The gases produced from the biomass gasification can be used for heat and power production. Alternatively, they can be used for ... -
Diffusion of CO2 through polymer membranes
(Chapter; Peer reviewed, 2020)The food industry uses polymers as packaging to protect and maintain high quality and freshness of the product during distribution and storage. Polymers are permeable by gases like O2, CO2 and water vapour. In this paper, ... -
The Effect of Climate and Orientation on the Energy Performance of a Prefab House in Norway
(Chapter, 2023)Norway has a wide range of climatic conditions throughout the country. The climate varies from coastal to inland areas. Geographic latitude and longitude, as well as the gulf stream oceanic flow, account for this phenomenon. ... -
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 ... -
Fusion of Body Sensors’ Data and Video Images in Assistive Technology
(Chapter, 2019)Modern innovations in the design of sensors and the convergence of computing, cognition and communications have led to many new possibilities in incorporating AI-techniques in Assistive Technology (AT) for elderly people. ... -
Implied safety level in design codes for monopile offshore wind turbines: parametric study on the effect of partial safety factors
(Chapter, 2023)Offshore wind structures are subjected to complicated loads and load effects, which demand comprehensive numerical modelling representation of the physics. There is interdependence between loads, load-effects, and structural ... -
Mathematical Modeling and Optimization of a Vehicle Crash Test based on a Single-Mass
(Chapter, 2014)In this paper mathematical modelling of a vehicle crash test based on a single mass is studied. The models under consideration consist of a single mass, a spring and/or a damper. They are constructed according to the ... -
Mesh Sensitivity Analysis of an Entrained Flow Biomass Gasifier: A CPFD Study
(Chapter, 2022)Biomass such as agricultural waste, forestry waste, municipal solid waste, and industrial waste, are renewable energy sources that may be used to produce biofuels. Biomass gasification is an effective and promising technology ... -
Off-field Testing of Grid Scenarios at Medium Voltage in Flexible AC Transmission Systems involving Wind Energy
(Chapter, 2020)As a result of the geographical location of north-western Germany, the local grid operator EWE NETZ has a pioneer role with respect to the integration of renewable energy sources in existing AC transmission systems. About ... -
On Detection of Yaw and Roll Angle Information for Vehicle Oblique Crash using Hough Transform
(Chapter, 2014)When performing vehicle crash tests, it is common to capture high frame rate video (HFR) to observe the vehicle motion during the impact. Such videos contain a lot of information, especially when it comes to geometric data. ... -
Simulation of Oil Recovery Through Advanced Wells Using a Transient Fully Coupled Well-Reservoir Model
(Chapter, 2023)Oil recovery can be enhanced by maximizing the well-reservoir contact using long horizontal wells. One of the main challenges of using such wells is the early breakthrough of unwanted fluids due to the heel-toe effect and ... -
Velocity and turbulence measurements of oil-water flow in horizontal and slightly inclined pipes using PIV
(Chapter; Peer reviewed, 2009)Oil-water flows in horizontal and slightly inclined pipes are investigated using Particle Image Velocimetry (PIV). PIV offers a powerful non-invasive tool to study such flow fields. The experiments are conducted in a 15 m ...
