Ultrasound intensified CO2 desorption from pressurized loaded monoethanolamine solutions. I. parameters investigation and modelling
(Journal article; Peer reviewed, 2018)CO2 stripping from loaded monoethanolamine (MEA) aqueous solutions intensified by means of ultrasound was investigated in a lab-scale kettle reboiler with both gas and liquid continuous operations. The reboiler operating ... -
Ultrasound intensify CO2 desorption from pressurized loaded monoethanolamine solutions. II. Optimization and cost estimation
(Journal article; Peer reviewed, 2019)Optimization and cost estimation were performed for the use of ultrasound for intensifying CO2 reboiler stripping from lean monoethanolamine (MEA) aqueous solutions at 1.0 barg. This work was based on typical industrial ... -
Use of recycled materials as mid layer in three layered structures-new possibility in design for recycling
(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 ... -
Using Image Processing for Flame Diagnostics
(Journal article; Peer reviewed, 2017)An image processing routine was developed to determine the flame height of a hydrogen jet flame. Two different techniques was tested, where one where based on Wiens distribution of a black body and one based on intensity ... -
Using the quantum yields of photosystem II and the rate of net photosynthesis to monitor high irradiance and temperature stress in Chrysanthemum (Dendranthema grandiflora)
(Journal article; Peer reviewed, 2015)Under a dynamic greenhouse climate control regime, temperature is adjusted to optimise plant physiological responses to prevailing irradiance levels; thus, both temperature and irradiance are used by the plant to maximise ... -
Validation of results from Barracuda® CFD modelling to predict the minimum fluidization velocity and the pressure drop of Geldart A particles
(Journal article; Peer reviewed, 2017)Fluidization characteristics such as the minimum fluidization velocity and the bed pressure drop are important for the design of an efficient fluidized bed. These characteristics can be measured experimentally, but also ... -
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 ... -
Waste heat availability in the raw meal department of a cement plant

Wave Front Tracking using Template Matching and Segmented Regression
(Peer reviewed; Journal article, 2017)An experimental study was designed to measure shock waves (supersonic gas flow) in a shock tube. A high-speed camera captured images of the shock waves, at a framerate up to 500,000 frames per second. with respect to the ... -
What effect does rehabilitation of wastewater pipelines have on the share of infiltration and inflow water (I/I-water)?
(Peer reviewed; Journal article, 2021)Infiltration and inflow water (I/I-water) is a big challenge in sewage systems in many countries. I/I-water above an acceptable level indicates that the sewage system is not functioning properly. I/I-water leads to increased ... -
Work Placement in Higher Education – Bridging the Gap between Theory and Practice
(Peer reviewed; Journal article, 2019)During the engineering education, the focus is on theoretical knowledge and less on the practical competence to be a professional engineer. To lead higher education into the future, it is critical to develop models and ...
