Data-Driven Methods for Investigation of Oceanic Whitecaps
Drndic, Kenan (Master thesis, 2024)Denne avhandlingen hadde som mål å besvare to primære forskningsspørsmål: nøyaktigheten av PIV-hastighetsfeltestimater av skumtoppermets overflate på havet og deres korrelasjon med øyeblikkelige vindhastighetsmålinger, ... -
Fysikk som symbolsk form – Cassirers vitenskapsfilosofi og dens relevans for moderne fysikk
Aarnes, Jørgen Røysland (Master thesis, 2022)I denne masteroppgaven besvares spørsmålet om hvordan vi kan forstå den moderne fysikkens objektivitet og fysikkens plass i vår helhetlige erkjennelse, ved hjelp av Ernst Cassirers vitenskapsteori og kulturfilosofi. Cassirers ... -
Fysikkens estetikk – om skjønnhet og estetisk velbehag i matematisk fysikk
Aarnes, Jørgen Røysland (Bachelor thesis, 2020) -
High-order overset grid method for detecting particle impaction on a cylinder in a cross flow
Aarnes, Jørgen Røysland; Haugen, Nils Erland L; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2019)An overset grid method was developed to investigate the interaction between a particle-laden flow and a circular cylinder. The method is implemented in the Pencil Code, a high-order finite-difference code for compressible ... -
Improving Accuracy of Computational Light Scattering Simulations by Improved Numerical Integration
Aarnes, Jørgen Røysland (Master thesis, 2014)Numerical integration plays an important role in many large scale physics simulations, yet the accuracy of such computations are often overlooked when the integrator routine is implemented---if the integration result itself ... -
Numerical investigation of free-stream turbulence effects on the transition-in-wake state of flow past a circular cylinder
Aarnes, Jørgen Røysland; Andersson, Helge Ingolf; Haugen, Nils Erland L (Journal article; Peer reviewed, 2018)We investigate how a turbulent free-stream (TFS) affects the transition-in-wake state of flow past a cylinder. Direct numerical simulations of a decaying TFS flow past a cylinder have been performed, where the intensity ... -
Simple Geometry – Complex Flow A computational study of turbulent particle-laden flows impinging on a cylinder
Aarnes, Jørgen Røysland (Doctoral theses at NTNU;2018:307, Doctoral thesis, 2018)Direct numerical simulations were performed to study the effects of free-stream turbulence on different flow regimes past a circular cylinder. The focus was on the transition-in-wake state of the flow and particle impact ... -
Thermophoresis and its effect on particle impaction on a cylinder for low and moderate Reynolds numbers
Haugen, Nils Erland L; Krüger, Jonas; Aarnes, Jørgen Røysland; Karchniwy, Ewa Malgorzata; Klimanek, Adam (Peer reviewed; Journal article, 2021)The effect of thermophoresis on the impaction of particles on a cylinder is investigated for different particle sizes, particle conductivities, temperature gradients and for Reynolds numbers between 100 and 1600. This is ...
