Numerical analysis of erosion due to nanoparticles in a pipe elbow
(Journal article; Peer reviewed, 2018)Flows of fluids laden with small particles in pipes are common in industry. An interesting and still unexplored issue is erosion of walls due to impact of particles. The main focus of our research was on nanoparticles. ... -
Numerical analysis of fire-driven smoke plumes in the atmosphere
(Master thesis, 2017)Plumes originating from fires may serve as a risk for people and environmental safety. Depending on what fuels a fire the content of the plume will vary [1]. From simple carbonaceous soot particulates, known to cause ... -
A numerical damped oscillator approach to constrained Schrödinger equations
(Journal article; Peer reviewed, 2020)This article explains and illustrates the use of a set of coupled dynamical equations, second order in a fictitious time, which converges to solutions of stationary Schrödinger equations with additional constraints. In ... -
Numerical investigation of a radially cooled turbine guide vane using air and steam as a cooling medium
(Peer reviewed; Journal article, 2021)Gas turbine performance is closely linked to the turbine inlet temperature, which is limited by the turbine guide vanes ability to withstand the massive thermal loads. Thus, steam cooling has been introduced as an advanced ... -
Numerical investigation of direct absorption solar collectors based on carbon black nanofluids
(Peer reviewed; Journal article, 2023)A novel model of a rectangular direct absorption solar collector (DASC) based on carbon black (CB) nanofluids for concentrated solar power is presented herein. Distributions of temperature, velocity, volume fraction of ... -
Numerical Investigation of the Required Quantity of Inert Gas Agents in Fire Suppression Systems
(Peer reviewed; Journal article, 2020)Inert gas agents have the potential to be widely used in fire suppression systems due to health and safety concerns associated with active chemicals. To suppress fire while minimizing hypoxic effects in an occupied area, ... -
Numerical modelling of permafrost spring discharge and open-system pingo formation induced by basal permafrost aggradation
(Journal article; Peer reviewed, 2020)In the high Arctic valley of Adventdalen, Svalbard, sub-permafrost groundwater feeds several pingo springs distributed along the valley axis. The driving mechanism for groundwater discharge and associated pingo formation ... -
Numerical Modelling of Two-phase Flow in a Gas Separator Using Eulerian-Lagrangian Flow Model
(Peer reviewed; Journal article, 2021)Gravity-driven separators are broadly used in various engineering applications to remove particulate matters from gaseous fluids to meet legislation demands. This study represents a detailed numerical investigation of a ... -
Numerical models of multiphase flows with sticky particles
(Doctoral thesis, 2024)Plugging caused by adhesive particles remains an important problem in multiphase fluid dynamics for decades and needs extensive theoretical research. This work aims to investigate this problem using a coupled Computational ... -

Numerical Simulation of Fluid Flow inside the Flow Control Valve
(Journal article, 2019)Hydraulic valves are widely used in many branches and they are still developed and improved. Due to the problem with verification of flow phenomena which appears during valves operation numerical simulations methods are ... -
Numerical simulations of the sliding impact between an ice floe and a ship hull structure in ABAQUS
(Peer reviewed; Journal article, 2022)This paper studies the hull structural responses of a steel grillage subjected to sliding ice loads, which have been rarely investigated in the literature. Sliding ice loads are modelled using nonlinear finite element ... -
Numerical study of downscaling the Runehamar tunnel fire te
(Bachelor thesis, 2016-06-14)An increase in tunnels in Norway, have brought forth a higher demand for safety measures, amongst others, fire safety. Experimental fire safety data from tunnels that contributes to solving engineering problems with low ... -
A numerical study of flow field and particle deposition in nasal channels with deviant geometry
(Peer reviewed; Journal article, 2021)Deviant geometry of nasal channels results in significant changes to nasal aerodynamics that alter flow resistance, sensation, and the ability to filter aerosols. The invasive, operative modification of nasal geometry might ... -
Numerical study of the airflow criterion of pressurization systems using Fire Dynamics Simulator
(Master thesis, 2020)Smoke control systems are used to prevent the spread of fire and smoke within buildings. Typical areas to be protected are the egress routes, atriums, and areas with larger fire loads. Smoke control systems prevent excessive ... -
A nutrient recommendation system for soil fertilization based on evolutionary computation
(Peer reviewed; Journal article, 2021)In agricultural production, soil characteristics play a vital role in maintaining fertility by allowing crops to develop better through root nutrition with minimal energy inputs. Nitrogen (N), Phosphorus (P), and Potassium ... -
