Improved model for solar heating of buildings
(Journal article; Peer reviewed, 2015-11-25)A considerable future increase in the global energy use is expected, and the effects of energy conversion on the climate are already observed. Future energy conversion should thus be based on resources that have negligible ... -
Improving bench scale design for polymerisation of green CO2-polymers
(Journal article; Peer reviewed, 2018)Plastic has become the most common material since the beginning of the 20th century and has become almost indispensable due to its durability, light weight and low costs. However, some of the characteristics also make the ... -
Improving bench scale pilot reactor design for polymerisation of green CO2-polymers
(Journal article; Peer reviewed, 2018)Plastic has become the most common material since the beginning of the 20th century and has become almost indispensable due to its durability, light weight and low costs. However, some of the characteristics also make the ... -
Improving gas distribution and evaporation in gas cooling tower at Norcem Brevik
(Peer reviewed; Journal article, 2020)In this work, the effect of the geometry of a GCT (Gas Cooling Tower) on the flue gas distribution in a cooling tower in Norcem, Brevik is investigated by using CPFD (Computational Particle Fluid Dynamics) modeling and ... -
Investigation of the segregation and mixing behavior of biomass in a bubbling fluidized bed reactor using a CPFD model
(Journal article; Peer reviewed, 2019)Segregation of biomass in a gasification reactor is an inevitable problem that can jeopardize the advantages such as uniform temperature control and proper mass circulation, and good solid-gas contacting area of the fluidized ... -
Linearization for Analysis of a Hydropower Model using Python API for OpenModelica
(Journal article; Peer reviewed, 2018)Even though almost all processes in the real world are described by nonlinear models, nonlinear theory for analysis of these models is far less developed than the theory for linear models. Therefore model linearization is ... -
Machine Learning in Python for Weather Forecast based on Freely Available Weather Data
(Journal article; Peer reviewed, 2018)Forecasting weather conditions is important for, e.g., operation of hydro power plants and for flood management. Mechanistic models are known to be computationally demanding. Hence, it is of interest to develop models that ... -
Methane from Syngas by Anaerobic Digestion
(Journal article; Peer reviewed, 2017)Anaerobic digestion (AD) is a prominent green technology used for methane production from organic waste. Previous studies have shown that the amount of CH4 produced during anaerobic digestion can be increased by adding ... -
Model Based Early Kick/Loss Detection and Attenuation with Topside Sensing in Managed Pressure Drilling
(Peer reviewed; Journal article, 2020)Early kick/loss detection is a crucial part of safe well control, and it plays a major role in the reduction of risk and non-productive time in drilling. In conventional drilling, topside sensing is used for early kick/loss ... -
Model uncertainty of interfacial area and mass transfer coefficients in absorption column packings
(Journal article; Peer reviewed, 2017)Uncertainty in model input parameters propagates through the model to make model output imprecision. Here, mathematical models used to calculate interfacial area and mass transfer coefficient for both random and structured ... -
modelica.university: A Platform for Interactive Modelica Content
(Journal article; Peer reviewed, 2017)The World Wide Web was conceived of as a medium for the expression and exploration of scientific and engineering ideas. However, much of the innovation in web technologies is now focused on consumer facing applications. Although ... -
Modeling and simulation of light oil production using inflow control devices
(Journal article; Peer reviewed, 2017)Light crude oil production is the most economical and is currently serving as benchmark together with medium crude oil. The most of the conventional oil fields in the worlds are either light or medium crude oil. Conventional ... -
Modeling and Simulation of Triclosan Kinetics and Distribution in Humans Using a PBPK Model
(Journal article; Peer reviewed, 2015-11-25)Personal care products (PCPs) such as soaps, perfumes, toothpastes, lotions, etc. contain various chemicals. Triclosan (TCS) is widely used as an antibacterial additive in PCPs. Traces of TCS are found in human plasma and ... -
Modeling and Simulation of Triclosan Kinetics and Distribution in Humans Using PBPK Model
(Journal article; Peer reviewed, 2018)Triclosan (TCS) has been used as an antibacterial additive in several personal care products (PCPs) for more than 40 years. In animals studies, it is observed that TCS in rats has adverse effects on the endocrine function ... -
Modeling for control of run-of-river power plant Grønvollsfoss
(Journal article; Peer reviewed, 2015-11-25)Design of optimal operation and control of a run-of-river hydro power plant depends on good models for the elements of the plant. River reaches are often considered to be shallow channels with free surface flow. A typical ... -
Modeling N/S ratio and temperature effects in simultaneous biological denitrification and sulfide oxidation
(Journal article; Peer reviewed, 2017)A model describing the simultaneous removal of NO3- and HS- by microorganisms is presented here. The oxidation of HS- (electron donor) can be controlled by the appropriate dosage of NO3-. The developed model, which includes ... -
Modelling and Simulation of Detection Rates of Emergent Behaviours in System Integration Test Regimes
(Peer reviewed; Journal article, 2021)System level testing generally lacks coverage due to cost of performing realistic tests on the “system as a whole”. This lack in test coverage gives rise to seemingly emergent aviour at system level. The interactions between ... -
