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, ... -
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 ... -
Mathematical sciences as symbolic form: the objects and objectivity of science in Ernst Cassirer’s philosophy of science and culture
Aarnes, Jørgen Røysland (Journal article; Peer reviewed, 2024)In this paper, I explore how Cassirer’s early and mature epistemology, philosophy of science, and philosophy of culture make up a coherent and comprehensive view of the mathematical sciences that is fruitful for understanding ... -
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 ...
