Numerical Analysis of Flow across Brush Elements Based on a 2-D Staggered Tube Banks Model
(Journal article; Peer reviewed, 2021)n order to improve efficiency in turbomachinery, brush seal replaces labyrinth seals widely in the secondary air system. A 2-d staggered tube bank model is adopted to simulate the gas states and the pressure character in ... -
Numerical analysis of fluid-added parameters for the torsional vibration of a Kaplan turbine model runner
(Journal article; Peer reviewed, 2017)The impact of fluid on the runner of a hydraulic turbine is a recurrent problem. Fully coupled fluid–structure simulations are extremely time-consuming. Thus, an alternative method is required to estimate this interaction ... -
Numerical analysis of hemodynamics in the left part of the heart, including simplified fluid-structure interaction methods
(Master thesis, 2010)The mitral valve is placed between the left atrium and ventricle. Both intra ventricular blood flow as well as valve dynamics are often subject to research. However, the inlet properties for such flows, which are created ... -
Numerical analysis of local and global responses of an offshore fish farm subjected to ship impacts
(Journal article; Peer reviewed, 2019)Due to limited nearshore areas and great impact to local ecosystems, the aquaculture industry is moving the fish farms into more exposed sea regions where the environmental conditions are much more severe. Like other ... -
Numerical analysis of mixed-mode rupture propagation of faults in reservoir-caprock system in CO2 storage
(Journal article, 2018)Injection-induced seismicity and caprock integrity are among the most important concerns in CO2 storage operations. Understanding and minimizing fault/fracture reactivation in the first place, and rupture growth/propagation ... -
Numerical Analysis of Mooring Systems for Floating Wind Turbines
(Master thesis, 2022)The world is progressing rapidly towards sustainable forms of energy, and the share of electrical energy produced from wind will grow exponentially in the coming years. Subsequently, floating wind turbines are moving towards ... -
Numerical analysis of non-linear oscillations of micrometre size fluid droplets
(Master thesis, 2014)Nonlinear oscillations of free viscous drops are investigated by solving the full Navier-Stokes equation using the finite element software COMSOL Multiphysics. Oscillations are investigated for droplets released form static ... -
Numerical Analysis of NREL 5MW Wind Turbine: A Study Towards a Better Understanding of Wake Characteristic and Torque Generation Mechanism
(Journal article; Peer reviewed, 2016)With the increased feasibility of harvesting offshore wind energy, scale of wind turbines is growing rapidly and there is a trend towards clustering together higher number of turbines in order to harvest maximum yield and ... -
Numerical analysis of pit-to-crack transition under corrosion fatigue using a stochastic pit generation algorithm
(Chapter, 2023)In numerical corrosion fatigue studies, the complex pit morphology is often idealized using an overly simplified geometry with a smooth surface because of the difficulties involved in modelling defects with the irregular ... -

Numerical Analysis of Primary Stability on Cementless Hip Prostheses
(Master thesis, 2012)Since the first Total Hip Arthroplasty (THA) performed in the 60's, it has been regarded among the most successful surgical procedures. When an un-cemented hip prosthesis is employed, the prosthesis is impacted into a ... -
Numerical analysis of stresses and displacements for the Tafjord slide, Norway
(Journal article; Peer reviewed, 2006)Numerical modelling has been used for analyzing stresses and displacements for the very steep and more than 1,000 m high Heggura rock slope near Tafjord, Norway where a disastrous 3 million m3 rock slide occurred in 1934. ... -
Numerical Analysis of the Dynamic Behaviour of Railway Catenary Systems in Accordance with Norwegian Conditions
(Master thesis, 2013)The dynamic behaviour of the railway catenary system is of great importance as the speed of the train increases. The aim for this study was to make a numerical model of the catenary system in three dimensions to be able ... -
