Flow in Pelton turbines
(Master thesis, 2013)The flow in Pelton turbines is subsonic, turbulent, multiphase (water, air, and water vapor from cavitation), has high speeds, sharp gradients, free surface and dynamic boundary conditions. A static grid is unsuitable for ... -
The flow in the induction and entrance regions of lab-scale wind farms
(Peer reviewed; Journal article, 2023)With the increasing demand for wind energy, it is important to be able to understand and predict the available wind resources. To that end, the present wind tunnel study addresses the flow in the induction and entrance ... -
Flow pattern transitions in and hysteresis effects of falling film flow over horizontal tubes related to LNG heat exchangers
(Journal article; Peer reviewed, 2015)Spiral wound heat exchangers with horizontal tube configurations are used extensively in the chemical, refrigeration, petroleum and food industry, and are core components in many natural gas liquefaction plants. For improved ... -
Flow streaming mediated particle separation inside a droplet induced by surface acoustic waves
(Master thesis, 2022)I nyere tid har manipulering av nanopartikler på nanoskala blitt et tema av stor interesse blant det vitenskapelige miljøet. Fordelene ved å bruke SAW representerer et stort fremskritt innen felt som biomedisin eller ... -
A fluid mechanic view on urban wind energy
(Doctoral theses at NTNU;2022:283, Doctoral thesis, 2022)The world energy demand is rising with an increasing need for renewable and sustainable energy sources. Wind energy plays a key role in this transition. Urban areas are largely unexploited for wind energy extraction. Urban ... -
Fluid selection and thermodynamic optimization of organic Rankine cycles for waste heat recovery applications
(Journal article; Peer reviewed, 2017)Organic Rankine cycles are effective to convert waste heat to power. One of the advantages and challenges of these cycles is that the most suitable working fluid and cycle configuration have to be selected for every ... -
Fluid sensitive nanoscale switching with quantum levitation controlled by a-Sn/b-Sn phase transition
(Journal article, 2018)We analyze the Lifshitz pressure between silica and tin separated by a liquid mixture of bromobenzene and chlorobenzene. We show that the phase transition from semimetallic α−Sn to metallic β−Sn can switch Lifshitz forces ... -
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 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 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 ... -
