A Control- and Estimation-Oriented Gravity Separator Model for Oil and Gas Applications Based upon First-Principles
Backi, Christoph Josef; Grimes, Brian Arthur; Skogestad, Sigurd (Journal article; Peer reviewed, 2018)We introduce a simple model for a gravity separator based on first principles. It can be used for controller design to control the levels of oil, water, and the gas pressure as well as observer design to estimate unmeasurable ... -
Augmented Microfluidic Dye Sensitized Solar Cells - Longevity and Performance Efficiency Investigation In Novel Architectures Through Synergizing Materials and Microfluidics
Rutkowski, Gregory (Master thesis, 2017)Dye-sensitized solar cells (DSSCs) have garnered increasing attention from scientists and engineers due to the potential of low cost and flexibility in terms of choice of constituent materials, along with increasing emphasis ... -
Characterization of the Electrical Resistivity and Water Sorption Properties of a Semiconducting Swelling Tape
Olsen, Maria Nicte Polanco (Master thesis, 2018)In presence of moisture and localized field enhancements water trees might develop within the polymeric insulation of HV subsea power cables. Water trees tend to grow unnoticeable and deteriorate the insulation properties ... -
Computer vision aided investigation of complex fluid physics
Gjerstad, Konrad (Master thesis, 2023)Å forstå fysikken til flerfasestrømmen av bobler-i-væske er viktig for utviklingen av mange kjemiske og biokjemiske prosessindustrier. Denne artikkelen diskuterer hvordan dyp læring, for eksempel kunstige nevrale nettverk, ... -
Microfluidic droplet detection via region-based and single-pass convolutional neural networks with comparison to conventional image analysis methodologies.
Rutkowski, Gregory Philip; Azizov, Ilgar; Unmann, Evan; Dudek, Marcin; Grimes, Brian Arthur (Peer reviewed; Journal article, 2022)As the complexity of microfluidic experiments and the associated image data volumes scale, traditional feature extraction approaches begin to struggle at both detection and analysis pipeline throughput. Deep-neural networks ... -
Microscopic Insight to Nonlinear Voltage Dependence of Charge in Carbon-Ionic Liquid Supercapacitors
Mehandzhiyski, Aleksandar Yordanov; Wang, Xuehang; Anquetil-Deck, Candy; Chen, De; Grimes, Brian Arthur (Journal article; Peer reviewed, 2021) -
Modeling and Analysis of a Batch Gravity Separation of an Oil and Water Emulsion
Espenes, Marius (Master thesis, 2014)A model for simulating the separation of an emulsion in a batch gravity settler was tested. This model is based on a population balance which considers a non-uniform droplet distribution, where coalescence occurs simultaneously ... -
Modeling Interfacial Mass Transfer during the Dynamic Evolution of the Drop Size Density Distribution of Emulsions in Turbulent Pipe Flow
Lædre, Torstein (Master thesis, 2016)Denne oppgaven har fokusert på å modelllere den dynamiske utviklingen av emulsjoners dråpestørrelsesfordeling i turbulent rørstrømning med og uten massebalansen for tensider. Først, ble smaspillet mellom koalesens og ... -
Multiscale modeling of mass transfer and adsorption in liquid-liquid dispersions. 1. Molecular dynamics simulations and interfacial tension prediction for a mixed monolayer of mono- and tetracarboxylic acids
Kovalchuk, Karina; Riccardi, Enrico; Grimes, Brian Arthur (Journal article; Peer reviewed, 2014)Phase space trajectories of protonated and deprotonated mono- and tetracarboxylic acid surfactants at an oil/water interface are obtained from molecular dynamics (MD) simulations and are employed to calculate the interfacial ... -
Multiscale modeling of mass transfer and adsorption in liquid-liquid dispersions. 2. application to calcium naphthenate precipitation in oils containing mono- and tetracarboxylic acids
Kovalchuk, Karina; Riccardi, Enrico; Grimes, Brian Arthur (Journal article; Peer reviewed, 2014)A dynamic multicomponent mass transport model is constructed and solved to determine the interfacial composition and bulk phase concentrations of surfactant mixtures containing a synthetic tetracarboxylic acid (BP10) and ... -
