Models for Predicting Average Bubble Diameter and Volumetric Bubble Flux in Deep Fluidized Beds
Agu, Cornelius Emeka; Pfeifer, Christoph; Eikeland, Marianne Sørflaten; Tokheim, Lars-André; Moldestad, Britt Margrethe Emilie (Journal article; Peer reviewed, 2018)The average bubble diameter and volumetric bubble flux give indications about the overall bed expansion in a fluidized bed. As these properties depend on the particle properties and fluidized bed regime, their accurate ... -
A Scoping Review on Environmental, Economic, and Social Impacts of the Gasification Processes
Barahmand, Zahir; Eikeland, Marianne Sørflaten (Peer reviewed; Journal article, 2022)In recent years, computer-based simulations have been used to enhance production processes, and sustainable industrial strategies are increasingly being considered in the manufacturing industry. In order to evaluate the ... -
Sensitivity Analysis and Effect of Simulation parameters of CPFD Simulation in Fluidized Beds
Bandara, Janitha; Nielsen, Henrik Kofoed; Moldestad, Britt Margrethe Emilie; Eikeland, Marianne Sørflaten (Journal article; Peer reviewed, 2018)Fluidized bed technology is broadly applied in industry due to its distinct advantages. CFD simulation of fluidized beds is still challenging compared to single-phase systems and needs extensive validation. Multiphase ... -
Simulation of air-biomass gasification in a bubbling fluidized bed using CPFD model
Timsina, Ramesh; Moldestad, Britt Margrethe Emilie; Eikeland, Marianne Sørflaten; Thapa, Rajan Kumar (Journal article; Peer reviewed, 2019)Biomass is a renewable energy source. Biomass gasification process produces producer gas, which can be further used for power generation or as raw materials for the production of secondary fuels. Experiment on the air ... -
Simulation of entrained flow gasification reactor with Multi Phase Particle in Cell (MP-PIC) approach
Timsina, Ramesh; Thapa, Rajan Kumar; Moldestad, Britt Margrethe Emilie; Eikeland, Marianne Sørflaten (Journal article; Peer reviewed, 2020)An Entrained flow gasification reactor is studied in this work. Entrained flow reactors are best suited for a feed with small particles at large capacity, at high temperatures, pressures and with short residence time. This ... -
Stepwise Analysis Of Gasification Reactions With Aspen Plus And Cpfd
Eikeland, Marianne Sørflaten; Thapa, Rajan Kumar (Journal article; Peer reviewed, 2017)The energy from biomass can be utilized through the thermochemical conversion processes of pyrolysis and gasification. Biomass such as wood chips is heated in a gasification reactor to produce a synthesis gas containing ... -
Techno-Economic and Life Cycle Cost Analysis through the Lens of Uncertainty: A Scoping Review
Barahmand, Zahir; Eikeland, Marianne Sørflaten (Peer reviewed; Journal article, 2022)Researchers have long been interested in developing new economic assessment methods to provide credible information and facilitate the sustainable development of new technologies and products. The techno-economic analysis ... -
Use of recycled materials as mid layer in three layered structures-new possibility in design for recycling
Radusin, Tanja; Nilsen, Jorunn; Larsen, Sondre; Annfinsen, Steffen; Waag, Charlotte; Eikeland, Marianne Sørflaten; Pettersen, Marit Kvalvåg; Fredriksen, Siw Bodil (Peer reviewed; Journal article, 2020)Challenges of using recycled polymer materials in food packaging are related both to the properties of the material and demanding safety issues for food contact materials. The aim of this research was to detect possible ...
