Flame propagation in dust clouds. Numerical simulation and experimental investigation
(Doctoral thesis, 2014-06-27)This dissertation describes the development and validation of a methodology for estimating the consequences of accidental dust explosions in complex geometries. The approach adopted entails the use of results from standardized ... -
Flame Propagation in Dust Clouds: Challenges for Model Validation
(Conference lecture, 2010)Modelling of industrial dust explosions poses a formidable challenge to researchers and safety engineers. Whereas current best practice with respect to modelling the consequences of vapour cloud explosions in the petroleum ... -
Flavour structure of R-violating neutralino decays at the LHC
(Peer reviewed; Journal article, 2011-07-15)We study signatures of R-parity violation in the production of supersymmetric particles at the LHC, and the subsequent decay of the lightest neutralino being the end product of a supersymmetric cascade decay. In doing so, ... -
Flavour tagged time dependent angular analysis of the \(B_s^{0} \rightarrow J/\psi \phi\) decay and extraction of \(\Delta\Gamma_s\) and the weak phase \(\phi_s\) in ATLAS
(Peer reviewed; Journal article, 2014-09)A measurement of the \(B_s ^{0}\rightarrow J/\psi \phi\) decay parameters, updated to include flavour tagging is reported using \(4.9 fb^{-1}\) of integrated luminosity collected by the ATLAS detector from \(\sqrt{s}= ... -
Flow Components and Initial State CM Fluctuations
(Peer reviewed; Journal article, 2012)At the LHC, the strong collective flow is observed in Pb+Pb collisions, as shown by the azimuthal correlations in the transverse-momentum distributions of the produced particles. We calculate flow components in a relativistic ... -
Flow dominance and factorization of transverse momentum correlations in Pb-Pb collisions at the LHC
(Peer reviewed; Journal article, 2017-04)We present the first measurement of the two-particle transverse momentum differential correlation function, \(P_2\equiv\langle \Delta p_{\rm T} \Delta p_{\rm T} \rangle /\langle p_{\rm T} \rangle^2\). in Pb-Pb collisions ... -
Flow loop study of a cold and cohesive slurry. Pressure drop and formation of plugs
(Journal article; Peer reviewed, 2023)Slurries of cohesive particles constitute a significant risk during subsea petroleum production due to their potential to plug the flow. This article describes a flow loop study of a slurry consistent with 0.23-mm ice ... -
Flow visualization of CO2 in tight shale formations at reservoir conditions
(Peer reviewed; Journal article, 2015-09-18)The flow of CO2 in porous media is fundamental to many engineering applications and geophysical processes. Yet detailed CO2 flow visualization remains challenging. We address this problem via positron emission tomography ... -
Flow vorticity in peripheral high-energy heavy-ion collisions
(Peer reviewed; Journal article, 2013-03-22)Vorticity development is studied in the reaction plane of peripheral relativistic heavy-ion reactions where the initial state has substantial angular momentum. The earlier predicted rotation effect and Kelvin Helmholtz ... -
Fluctuations of anisotropic flow in Pb+Pb collisions at √sNN = 5.02 TeV with the ATLAS detector
(Journal article; Peer reviewed, 2020-01-09)Multi-particle azimuthal cumulants are measured as a function of centrality and transverse momentum using 470 μb−1 of Pb+Pb collisions at sNN−−−√ = 5.02 TeV with the ATLAS detector at the LHC. These cumulants provide ... -
Fluid dynamics study of the Λ polarization for Au + Au collisions at √sNN = 200 GeV
(Journal article; Peer reviewed, 2020)With a Yang–Mills field, stratified shear flow initial state and a high resolution (3 + 1)D particle-in-cell relativistic (PICR) hydrodynamic model, we calculate the Λ polarization for peripheral Au + Au collisions at RHIC ... -

The FLUKA Monte Carlo code coupled with an OER model for biologically weighted dose calculations in proton therapy of hypoxic tumors
(Journal article; Peer reviewed, 2020)Introduction The increased radioresistance of hypoxic cells compared to well-oxygenated cells is quantified by the oxygen enhancement ratio (OER). In this study we created a FLUKA Monte Carlo based tool for inclusion of ... -
Fluorescence intensity and fluorescence lifetime measurements of various carbon dots as a function of pH
(Journal article; Peer reviewed, 2023)Measurement and monitoring of pH are essential in both the industry and academia. It is therefore important to continue developing novel, low-cost pH sensors that provide increased accuracy over long periods of time. ... -
