CFD simulation of the droplet size distribution of liquid‐liquid emulsions in stirred tank reactors
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)Predicting the drop size distribution (DSD) is essential in particulate flows such as emulsions as it affects mass transfer and heat transfer. In the current work we developed a novel numerical method to account for droplet ... -
CFD SIMULATIONS OF AN ADDITIONAL H2 COMBUSTOR FOR IMPROVING EFFICIENCY IN CHEMICAL LOOPING COMBUSTION POWER PLANTS
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Chemical looping combustion (CLC) is a promising technology for hydrocarbon fuel combustion with integrated CO2 capture. The CLC process imposes almost no direct energy penalty for separating CO2, but a large indirect ... -
CFD simulations of flow in random packed beds of spheres and cylinders: analysis of the velocity field
(SINTEF Proceedings;1, Chapter, 2015)In this work, we aim to better understand the flow patterns in a random arrangement of particles that might affect local mass transfer and effective reactor performance. Using the DEM code Grains3D, spherical or cylindrical ... -

CFD Study of Diffuse Ceiling Ventilation through Perforated Ceiling Panels
(Peer reviewed; Journal article, 2020)Diffuse Ceiling Ventilation (DCV) is a promising concept to address internal air quality and thermal comfort requirements in contemporary buildings. Sound-absorbing perforated ceiling panels are common in office rooms and ... -
A CFD Study of the Fluid Flow through Air Distribution Hoses in a Greenhouse
(Peer reviewed; Journal article, 2023)The indoor climate of a greenhouse provides the plants with favorable growing conditions that can result in faster growth and higher yields. Important parameters to control in a greenhouse are the temperature, the humidity, ... -
A CFD STUDY ON THE IMPACT OF BARRIERS AND NONUNIFORMITIES ON FURNACE TAPPING
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Tapping of slag and metal from metal producing furnaces are often inconsistent and it is difficult to predict the outcome of the process. Nonuniformities in the particle bed has been hypothesized as reasons for inconsistent ... -

CFD‐DEM modelling of blast furnace tapping
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)The campaign length of a blast furnace is limited by the hearth inner lining lifetime. In order to maximize the campaign length and ensure a good draining of hot metal and slag, a good understanding of the flow in the ... -
CFD‐simulation of boiling in a heated pipe including flow pattern transitions using a multi‐field concept
(SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)The paper presents the extension of the GENTOP model for phase transfer and discusses the sub-models used. Boiling flow inside a wall heated vertical pipe is simulated by a multi-field CFD approach. Sub-cooled water ... -
The challenge of a real, complex hybrid project
(Chapter, 2023)This paper explores the implementation process of a hybrid power plant project (HyPP) in the Philippines' deregulated and complex energy market. SN Aboitiz Power (SNAP) owns and operates the Magat HyPP which involves ... -
Challenges and approaches of performing canonical action research in software security: research paper
(Chapter, 2018)When studying work practices, it is important to obtain accurate and reliable information about how work is actually done. Action research is an interactive inquiry process that balances problemsolving actions implemented ... -
Challenges and emerging practices in design of automation
(Chapter, 2023)Automation is expected to improve efficiency, as well as increase safety and quality. However, as more automation is added to a system, the lower the situation awareness of the operators may be. In safety critical systems ... -
Challenges and Experiences with Applying Microsoft Threat Modeling in Agile Development Projects
