Fluid Structure Interaction Analysis of Abnormal Wave Slamming Events
(Master thesis, 2018)In critical sea states, slamming wave loads may cause severe structural damage to marine structures. The slamming loads are associated with fluid-structure impacts with high pressures and short durations. The structural ... -
Fluid Structure Interaction Analysis of Abnormal Wave Slamming Events
(Master thesis, 2022)I ekstreme sjøtilstandar kan bølgeslag påføre marine konstruksjonar store deformasjonar. Bølgeslag påfører konstruksjonen høge trykk med store variasjonar i tid og stad. Samankoplinga mellom hydrodynamiske laster og ... -
Fluid structure interaction aspects in obstructive sleep apnea patients
(Master thesis, 2017)In this master thesis, a comparative study of the feasibility of fluid-structure interaction (FSI) tools has been done in light of simulating the problem of obstructive-sleep apnea (OSA). Part of the study has been done ... -
Fluid Structure Interaction in a Pipe
(Master thesis, 2018)One of the recurring challenges concerning the development of fluid piping systems, is making them suitable for the task at hand. The system has to withstand all possible forces and motions associated with everyday use, ... -
Fluid structure interaction in circular blade cascade
(Master thesis, 2022)Når væske strømmer over en struktur, kan det utvikles uønskede virvler. I vannkraftindustrien er dette et stort problem som kan genereres i ledeskovler, der virvler går på tvers inn i løperen og forårsaker vibrasjoner. ... -
Fluid structure interaction of Francis-99 turbine and experimental validation
(Journal article; Peer reviewed, 2019)The ability to predict a francis runners dynamic response to the exciting forces is paramount to avoid unwanted disintegration of the turbines components. In this article, each of the principal factors contributing to the ... -
Fluid Structure Interaction Simulation on an Idealized Aortic Arch
(Master thesis, 2012)The aortic arch is at risk of several cardiovascular diseases, such as aortic dissection. Many of these risk factors are due to the fluid-structure interaction that occurs in the aorta. Fluid-structure interation (FSI) ... -
Fluid Topology in Pore Scale Two‐Phase Flow Imaged by Synchrotron X‐ray Microtomography
(Journal article; Peer reviewed, 2018)A flow experiment including drainage and imbibition by water and surfactant was performed on a water‐wet Berea sandstone. The three‐dimensional (3‐D) pore scale changes of the fluid configuration were captured under flow ... -
“Fluid transport through nanoporous media in the presence of phase transitions
(Doctoral theses at NTNU;2022:268, Doctoral thesis, 2022)Clean potable water is among the most precious commodities in the world. Even though water is not sparse on the planet’s surface, it is not sufficiently accessible for about 4 billion people, who are experiencing serious ... -
Fluid-Fluid Interfaces of Multi-Component Mixtures in Local Equilibrium
(Journal article; Peer reviewed, 2018)We derive in a new way that the intensive properties of a fluid-fluid Gibbs interface are independent of the location of the dividing surface. When the system is out of global equilibrium, this finding is not trivial: In ... -
Fluid-solid boundary handling using pairwise interaction model for non-newtonian fluid
(Journal article; Peer reviewed, 2018)In order to simulate fluid-solid boundary interaction for non-Newtonian Smoothed Particle Hydrodynamics (SPH) fluids, we present a steady and realistic fluid-solid boundary handling method using symmetrical interaction ... -
Fluid-Structure Interaction and Immersed Boundary Method for the Compressible Navier–Stokes Equations Using High Order Methods
(Doctoral theses at NTNU;2018:30, Doctoral thesis, 2017)There has been a growing interest in the study of biological flows in biomechanical systems in recent years. Such flows mostly appear in domains with complex geometries, flexible moving boundaries and usually involve ... -
Fluid-structure interaction effects during the dynamic response of clamped thin steel plates exposed to blast loading
(Peer reviewed; Journal article, 2021)This work presents results from a numerical investigation on the influence of fluid-structure interaction (FSI) on the dynamic response of thin steel plates subjected to blast loading. The loading was generated by a shock ... -
Fluid-Structure Interaction in Compressible Viscous Flow
(Master thesis, 2018)In this master's thesis a ghost-point immersed boundary method for the compressible Navier-Stokes equations using higher order summation by parts operators is described and implemented for two-way coupled fluid-structure ... -
Fluid-Structure Interaction Study of Vortex-Induced Vibration in Thermowells
(Master thesis, 2019)Termolommer er typisk utsatt for både statiske og dynamiske belastninger grunnet strømningen rundt den. De dynamiske kreftene som kommer fra virvelavløsningen kan bli problematiske dersom de har samme frekvens som ... -

Fluid-structure interactions in Francis turbines: A perspective review
(Journal article; Peer reviewed, 2017)Competitive electricity prices and reduced profit margins have forced hydraulic turbines to operate under critical conditions. The demand for extended operating ranges and the high efficiency of the turbine runners have ... -
Fluid-structure-interaction analysis of an ice block-structure collision
(Journal article; Peer reviewed, 2015)Due to climate change, production and transportation routes in Arctic regions are becoming more prevalent. When operating in Arctic waters, there is a significant risk of high energy encounters with smaller ice masses such ... -
