Large Time Step Methods for Hyperbolic Conservation Laws
(Doctoral theses at NTNU;2017:285, Doctoral thesis, 2017)The HLL (Harten–Lax–van Leer) and HLLC (HLL–Contact) schemes are extended to LTS-HLL(C) schemes. The LTS-HLL-type schemes for scalar conservation laws are defined in the numerical viscosity, flux-difference splitting and ... -
Large Time Step Methods for Hyperbolic Partial Differential Equations
(Master thesis, 2017)In this thesis we consider explicit finite volume methods that are not limited by the Courant-Friedrichs-Lewy (CFL) condition, referred to as large time step (LTS) methods. LeVequeproposed the first LTS method in the 1980 ... -
Large Time Step Roe scheme for a common 1D two-fluid model
(Journal article; Peer reviewed, 2017)We present the Large Time Step (LTS) extension of the Roe scheme and apply it to a standard two-fluid model. Herein, LTS denotes a class of explicit methods that are not limited by the CFL (Courant–Friedrichs–Lewy) condition, ... -
Large values of the argument of the Riemann zeta-function and its iterates

Large volume scanning laser induced fluorescence measurement of a bluff-body stabilised flame in an annular combustor
(Journal article; Peer reviewed, 2022)This study outlines a variant of three-dimensional OH planar laser-induced fluorescence and its application in characterising a single bluff body stabilised flame inside a 12 burner annular combustor. In this variant of ... -
Large-Deformation Behaviour of Thermoplastics at Various Stress States: An experimental and numerical study
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:298, Doctoral thesis, 2012)The large-deformation behaviour of thermoplastics has been studied by experimental tests and numerical simulations. The work herein is a part of a larger research project concerning constitutive modelling of polymers. A ... -
Large-Eddy Simulation of a Classical Hydraulic Jump: Influence of Modelling Parameters on the Predictive Accuracy
(Peer reviewed; Journal article, 2022)Results from large-eddy simulations of a classical hydraulic jump at inlet Froude number two are reported. The computations were performed using the general-purpose finite-volume-based code OpenFOAM®, and the primary goal ... -
Large-eddy simulations of cross-flow around ship sections
(Doctoral thesis at NTNU;2016:111, Doctoral thesis, 2016)This thesis reports numerical simulations of three-dimensional (3D) unsteady cross flow over two ship sections located side-by-side. The ship sections have different breadth and draft conditions which represent typical ... -
Large-eddy simulations of the flow over a semi-circular cylinder at Re = 50000
(Journal article, 2021)Large-eddy simulations (LES) of the flow over a semi-circular cylinder at a diameter-based Reynolds number 50000 and zero angle of attack are presented. In comparison with the prominent benchmark flows past circular and ... -
Large-eddy simulations of the flow past a bluff-body with active flow control based on trapped vortex cells at Re = 50000
(Peer reviewed; Journal article, 2023)We investigate a novel flow control concept, which allows to govern bluff-body wake dynamics and the laminar–turbulent transition by suppressing vortex shedding and obtaining the mostly detached flow. Large-eddy simulations ... -
Large-effect loci mediate rapid adaptation of salmon body size after river regulation
(Peer reviewed; Journal article, 2022)Understanding the potential of natural populations to adapt to altered environments is becoming increasingly relevant in evolutionary research. Currently, our understanding of adaptation to human alteration of the environment ... -
Large-scale Agile Software Development: An Exploratory Case Study of Changes In Agile Practices and Its Effects on Inter-team Coordination
(Master thesis, 2020)Smidige metodikker ble opprinnelig laget for mindre IT-prosjekter bestående av ett team. I de senere årene har smidige metodikker også blitt brukt på prosjekter i stor skala. Dette har forårsaket store smidige prosjekter ... -
Large-scale analysis of orthologs and paralogs in viruses and prokaryotes
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:109, Doctoral thesis, 2011)Storskala-analyse av ortologer og paraloger i virus og prokaryoter Jordens organismer kan deles inn i to grupper: de ikke-cellulære (virus) og de cellulære (prokaryoter og eukaryoter). Genomene til disse øker i kompleksitet; ... -
Large-scale CO2 Injection Analysis: understanding pressure variation in multiple compartments using analytical and computational analysis approaches
(Master thesis, 2022)Injecting carbon dioxide into deep saline aquifers and then storing it by physically and chemically trapping, is one viable strategy for reducing greenhouse gas emissions and mitigating global warming. To ensure the security ... -
Large-Scale Electron Correlation Calculations: Rank-Reduced Full Configuration Interaction
(Journal article, 2018)We present the rank-reduced full configuration interaction (RR-FCI) method, a variational approach for the calculation of extremely large full configuration interaction (FCI) wave functions. In this report, we show that ... -
Large-Scale Experimental Wind-Driven Rain Exposure Investigations of Building Integrated Photovoltaics
(Journal article; Peer reviewed, 2013)Building integrated photovoltaics (BIPVs) are photovoltaic materials that replace conventional building materials in parts of the building envelopes, such as roofs or facades, i.e. the BIPV system serves dual purposes, as ... -
Large-scale external validation and comparison of prognostic models: An application to chronic obstructive pulmonary disease
(Journal article; Peer reviewed, 2018)Background External validations and comparisons of prognostic models or scores are a prerequisite for their use in routine clinical care but are lacking in most medical fields including chronic obstructive pulmonary disease ... -
Large-scale genomics unveil polygenic architecture of human cortical surface area
(Journal article; Peer reviewed, 2015)Little is known about how genetic variation contributes to neuroanatomical variability, and whether particular genomic regions comprising genes or evolutionarily conserved elements are enriched for effects that influence ... -
Large-Scale Granulation of CaO-Based Pellets for High-Temperature Carbon Dioxide Capture
